The Hammond-Leffler Postulate,when Applied to Nucleophilic Substitutions and Elimination Reactions,states

Multiple Choice

The Hammond-Leffler postulate,when applied to nucleophilic substitutions and elimination reactions,states that:

A) a negatively-charged nucleophile is stronger than its conjugate acid.
B) polar aprotic solvents strongly accelerate the rate of S_N2 processes.
C) bimolecular nucleophilic substitutions are 2^nd order kinetically.
D) the transition state for an endergonic reaction step (one accompanied by an increase in free energy) resembles the product of that step.
E) elimination reactions will always compete with nucleophilic substitution reactions.
