Q. In an SN2 reaction, which of the following substrates would react the fastest with a nucleophile?
A.
tert-butyl chloride
B.
isopropyl bromide
C.
ethyl chloride
D.
methyl iodide
Solution
Methyl iodide reacts the fastest in an SN2 reaction due to minimal steric hindrance and the good leaving ability of iodide.
