Chemistry 30Organic Chemistry Notes
A. Carbon Compounds30-C1.1k define organic compounds as compounds containing carbon, recognizing inorganic
exceptions such as carbonates, cyanides, carbides and oxides of carbon
organic compounds are those in which carbon atoms are almost always bonded to each other, to hydrogen atoms and a few other atoms (O, N, S, P)
inorganic exceptions are the oxides of carbon, carbonates, cyanides and carbides (no C-C bonds or C-H bonds)eg) CO2, CaCO3, NaCN, SiC
there are millions of organic compounds and all contain covalent bonds carbon is unique for two reasons:
a) it can bond with other carbon atoms to form long chains, rings, spheres, tubes, sheets etc.
b) it can form combinations of single, double and triple bonds (no other element does this!!!!)
recall polarity and intermolecular forces from the chemical bonding unit polar bonds are formed when there is an uneven pull on e
polar compounds are formed when the polar bonds within a molecule do not cancel each other out
the presence of dipole-dipole forces and hydrogen bonding will allow polar compounds to dissolve in water, since it is also polar
non-polar compounds only have LD forces between molecules and will not dissolve in water
30-C1.2s perform an experiment to compare the properties of organic compounds with inorganic compounds, considering properties such as solubility, viscosity, density, conductivity and reactivity
B. Structural Isomers30-C1.5k define structural isomerism as compounds having the same empirical formulas, but
with different structural formulas, and relate the structures to variations in the properties of the isomers
isomers are compounds with the same molecular formula but a different structure
Example 1Draw the three structural isomers for C5H12.
1. 2. 3.
Example 2Draw three structural isomers for C4H8F2.
1. 2. 3.
30-C1.3s compile and organize data to compare the properties of structural isomers
different structures result in different properties the arrangement of the atoms determines the types of intermolecular
attractions which then determines properties such as boiling point and solubility in water
ExampleDraw two isomers of C3H8O. Which one would have a boiling point of 7.4C and which would have a boiling point of 82.5C? Explain why the boiling points are so different.

1. Properties30-C1.3s interpret the results of a test to distinguish between a saturated and an unsaturated
aliphatic, using aqueous bromine or potassium permanganate solutions
nonpolar not soluble in water lower boiling point than corresponding alkane because they have fewer
e which makes the LD forces of attraction weakereg) ethane BP = 88.6C ethene BP = 103.8C
more reactive than alkanes double bond has more e- in the same area greater repulsion and
bond less stable diagnostic test: use KmnO4(aq) or Br2(l) ***alkenes (double bond) will

30-C1.4k identify types of compounds from the hydroxyl, carboxyl, ester linkage and halogen functional groups, given the structural formula
F. Alcohols R - OH
organic compounds with one or more OH (hydroxyl) groups
1. Properties have much higher boiling points than corresponding aliphatics
because of hydrogen bonding!eg) methane (CH4) BP = 162C
methanol (CH3OH) BP = 65C polar the –OH end of the alcohol is polar while the carbon chain end is
not small alcohols are soluble in water and large alcohols are not
2. Uses antifreeze, rubbing alcohol, beverages, moistening agent
3. Naming number the longest carbon chain containing the hydroxyl group so
the –OH group gets the lowest number aliphatic name (without “e” at end) + “OL” give the number for the carbon where the –OH group is found
between the parent name and the suffix if there is more than one hydroxyl group, use a prefix (di, tri,
tetra) to indicate the number of OH groups and place the numbers between the parent name and the suffix***Note, if the suffix starts with a vowel, drop the “e” on the parent name; if the suffix starts with a consonant, keep the “e” on the parent name

groups many are toxic and dangerous

metals, neutralize bases
2. Uses recycling rubber – methanoic acid vinegar – ethanoic (acetic) acid rust remover – oxalic acid fruits – citric acid

I. Esters
where R can be a carbon chain or hydrogen and R’ can be a carbon chain
combination of a carboxylic acid and an alcohol
1. Properties polar small esters dissolve in water, large esters do not boiling points slightly lower than corresponding carboxylic acids and
alcohols due to lack of hydrogen bonding very volatile which allows them to generate aromas
2. Uses flavouring agents
3. Naming identify the alcohol used to make the ester change the alcohol name to the corresponding alkyl name
eg) methanol would become methyl identify the carboxylic acid the ester was made from drop the “oic acid” and replace with “oate”
eg) butanoic acid would become “butanoate” put the two names together with a space in between
eg) methyl butanoate you can have branches on esters…they follow the alphabetical rule,
numbering begins at the O end of the alcohol and the C=O end of the carboxylic acid

6. Polymerization Reactions30-C1.2sts explain that science and technology have influenced, and been influenced by,
historical development and societal needs30-C2.3k define, illustrate and provide examples of monomers, polymers and polymerization
in living systems and nonliving systems30-C2.3s draw or use models to illustrate polymers
a monomer is a simple molecule that forms the base unit for a polymer
a polymer is a very, very long molecule formed by the covalent bonding of bazillions of monomers
depending on the polymer, the monomers that make it up can be the same or different
polymers can be natural eg) carbohydrates, proteins, DNA
polymers can be synthetic eg) nylon, PVC, Teflon, polyester
polymers that can be heated and molded into specific shapes are commonly called plastics
plastics are one type of synthetic compound that has been of great benefit to society (although there are also problems associated with then)
the names of polymers are the monomer name with “poly” in front many have classical names instead of IUPAC names
Addition Polymers formed when the electrons in double or triple bonds in the monomer
units are rearranged the polymer is the only product formed

L. Petroleum Refining30-C1.7k describe, in general terms, the physical, chemical and technological processes used
to separate organic compounds from natural mixtures or solutions30-C2.1sts explain how science and technology are developed to meet societal needs and
expand human capability
Alberta has vast reserves of petroleum in the form of natural gas, crude oil and oil sand deposits
most of this petroleum is refined and then burned as fuel petrochemicals, basic hydrocarbon raw materials such as ethane and
propene, are also used in the production of plastics refining of petroleum separates the crude mixture into purified
components fractional distillation is used to separate the components distillation works because of the different boiling points of the
components of petroleum the lighter the molecule and the lower the boiling point, the higher it
rises in the tower (asphalt, fuel oil, wax at bottom; gasoline at top) there are two types of reactions in petroleum refining:
1. Cracking breaks long chain hydrocarbons into smaller units cracking requires heat and pressure there are many different types of cracking reactions, forming different
products (alkanes, alkenes)eg) catalytic cracking, steam cracking, hydrocracking
hydrocracking requires H2(g)
Examples:1. C17H36 + H2 C9H20 + C8H18 cat
2.
CH3 CH2 CH2 CH3 + cat
+ CH3 CH2 CH3 H2CH3 CH2 CH2 CH2 CH3 CH2 CH2
2. Reforming small hydrocarbons are joined to make larger molecules requires heat and pressure there are several types of reforming reactions
eg) alkylation to produce “high octane” gasoline all reforming reactions produce H2(g)
Examples:
1. C7H16 + C12H26 C19H40 + H2
2. ethane + octane decane + hydrogen gas
30-C1.1s design a procedure to separate a mixture of organic compounds, based on boiling point differences
