Question

out of CH2=CHBr and CH2-CH-CH2Br which would be hydrolysed more easily and why?

Open in App

Solution

Dear Student,
The hydrolysis of halides is a nucleophilic reaction in which hydroxide is a nucleophile. The ease of hydrolysis depends upon the stability of carbocation formed.
In case of CH₃CH₂CH₂Br a primary carbocation is formed while in case of CH₂=CHBr a vinylic carbocation is formed .
The vinylic carbocation is less stable than primary alkyl carbocation hence CH₃CH₂CH₂Br is hydrolysed easily.
Regards!
