Question

sn1 reaction explain
​

Answer 1

An Sn1 reaction is a reaction that depends on the substrate and it is a 2-step process.

1. Departure of the leaving group and the formation of carbocation intermediate

2. A weak nucleophile comes in and inserts itself into the compound

They normally occur in polar protic solvents and they generally favor stable carbocations so tertiary > secondary > primary > methyl

For example, let us say you have 2-bromo-2-methylpropane. The rate determining step is the dissociation of this species into a positively charged ion. (CH3)C+ is the carbocation and the LG is Br-

Answer 2

it is a nucleophilic substitution reaction which involves two step first rate determination which is slow hindrance effect may effect the reaction
