Rate of `SN^1`

A

`S gt P gt Q gt R`

B

`R gt Q gt P gt S`

C

`Q gt R gt P gt S`

D

`S gt Q gt P gt R`

Text Solution

Verified by Experts

The correct Answer is:
B
Rate of `S_(N)1` reaction depends on following factors :
(a) As the stability of cation increases rate of reaction increases
Rate of reaction increases with better leaving groups
(c ) Electron donating groups increases rate of reaction.

The rate of SN^2 reaction depends on the effectiveness of the nucleophile in ejecting the leaving group. Nucleophilicity is the affinity for C atom, while basicity is the affinity for proton. In both cases, a new bond is formed. If a new bond is formed between the anion and proton, the specied acts as a base. If a new bond is formed between the anion and C atom, the species acts as nucleophile. Which of the following compounds gives SN^1, SN^2 , and SN^2 mechanisms ?
