Q 5. Which of the following doesn’t respond to
schiff’s reagent test ?
(A) (B) 3CH CHO
(C) (D) All of these
Q 6. In schiff’s reagent test, colom change ocur as
(A) Red blue red
(B) Red colourless
(C) Red Colourless green
(D) Red Colourless Red
Q 7. Which of the following doesn’t respond to
sodium nitropruside test ?
(A) 3CH CHO (B) HCHO
(C) ArCHO (D)
Q 8. An organic compound A, C6H10O. On reaction
with CH3MgBr followed by acid treatment gives
compound B. The compound B on ozonolysis
gives compound C, which in the presence of a
base gives 1-acetyl cyclopentene D. The
compound B on reaction with HBr gives
compound E. Write the structures of A, B, C, and
E. Show how D is formed by C.
Q 9. An alkene (A) on ozonolysis yields acetone and
an aldehyde. The aldehyde is easily oxidized to
an acid (B). When B is treated with bromine in
presence of phosphorous it yields a compound
(C) which on hydrolysis gives a hydroxyl acid
(D). This acid can also be obtained from acetone
by the reaction with hydrogen cyanide followed
by hydrolysis. Identify the compounds A, B, C
and D. [IIT JEE 1982]
Q 10. A hydrocarbon A (M.F. C5H10) yields 2-
methylbutane on catalytic hydrogenation. A adds
HBr (in accordance with Markownkoff,s rule) to
form a compound B which on reaction with silver
hydroxide forms an alcohol C, C5H12O. Alcohol
C on oxidation gives a ketone D. Deduce the
structures of A, B, C and D and show the reaction
involved. [IIT JEE 1988]
Q 11. A ketone A which undergoes haloform reaction
gives compound B on reduction. B on heating
with sulphuric acid gives compound C, which
forms mon ozonide D. D on hydrolysis in
presence of zinc dust gives only acetaldehyde.
Identify A, B and C. Write down the reactions
involved. [IIT JEE 1989]
Q 12. An organic compound A, C8H6, on treatment with
dilute sulphuric acid containing mercuric
sulphate gives a compound B, which can also be
obtained from a reaction of benzene with an acid
chloride in the presence of anhydrous aluminium
chloride. The compound B, when treated with
iodine in aqueous KOH, yields C and a yellow
compound D. Identify A, B, C and D with
justification. Show how B is formed from A.
[IIT JEE 1994]
Q 13. An aldehyde A(C11H8O), which does not undergo
self aldol condensation, gives benzaldehyde and
two moles of B on ozonolysis. Compound B, on
oxidation with silver ion gives oxalic acid.
Identify the compounds A & B. [IIT JEE 1998]
