Question

Question: Order each of the following sets of compounds with respect to reactivity:

a.

Short answer

Answer

Step-by-step solution

SN2 reaction

It is a nucleophilic substitution reaction in which old bond is break and new bond is formed both the process occur simultaneously. Hence, it’s a single step reaction.

The two reacting species are involved in the rate determining steps.

Reactivity towards SN2 reaction

As the reaction is single step reaction so, no intermediate is formed andS_N2 occur fast with primary alkane than secondary alkane.

S_N2 occur fast with those reacting species which have best leaving group

So,

Reactivity order
