Referring to E/Z nomenclature, which of the following statements is not correct?

trichloromethyl priority > iodine priority

bromine priority > chlorine priority

isopropyl priority > methyl priority

deuterium priority > hydrogen priority

ethyl priority > methyl priority

Referring to E/Z nomenclature, which of the following priority rules is not correct?

If two substituents are attached by the same atom (a tie), you should compare the priority of the atoms attached to the tied atoms.

If an atom is doubly bonded to another atom, it should be treated as two single bonds to that atom.

Atoms with higher atomic numbers have higher priority.

The priority of isotopes is determined by their natural abundance.

Which of the following reagents is not a nucleophile?

methylamine

water

bromide ion

hydroxide ion

bromine atom

Which of the following does not use curved arrows correctly?

Which statement about curved arrows is not correct?

Curved arrows are drawn to indicate the movements of electrons.

Curved arrows always start at an atom.

Arrows are drawn away from negative charges and/or toward positive charges.

Several curved arrows might have to be used to describe one reaction.

The arrow is drawn in the direction of the electron flow.

Which statement is not true?

In the transition state, the bonds that break and form are partially broken or partially formed, respectively.

The structure of the transition state is between the structures of the reactants and products.

The activation energy for a reaction is equal to the energy difference between the energy of the reactants and the energy of the transition state.

The transition state is more similar in structure to the species that it is closer to energetically.

The transition state structure always resembles the starting materials more closely than it resembles the products.
