Homework Answers
Answer:-
option a): "2-butanone" is correct answer.
Explanation:-
SN2 reactions are generally favoured by polar aprotic solvents like acetone, DMSO (dimethyl sulphoxide), 2-butanone, DMF (dimethyl formamide),etc. Aprotic solvents cannot form hydrogen bonds, thus , they don't solvate nucleophiles (anions) involved in SN2 reactions. Anions are highly solvated by protic solvents through hydrogen bonding. As a result, reaction rate for SN2 reactions are very fast with anionic nucleophiles in aprotic solvents.
Also, aprotic solvents stabilize the transition state for SN2 reactions.
