Question

Arrange decreasing order of reactivity of these compounds for nucleophilic substitution reaction (I) (II) C H 3 – C H 2 – O T s (III) (IV)

TestHub · Accepted Answer

Rate of nucleophilic substitution reaction depends on nature of leaving group. Weak conjugate bases are good leaving groups C F 3 - S O 3 - > T s O - > - O H is leaving group order.
