Question

which alkyl halide follows only sn2 hydrolysis mechanism

Answer 1

it stands for bimolecular

Answer 2

Hey dear,

● Answer -
Primary alkyl halides prefer SN2 reaction due to less steric hindrance.


● Explanation -
- SN2 reaction is a bimolecular nucleophilic substitution reaction in which simultaneous bond-making and bond-breaking steps occur.
- SN2 reactions are greatly retarded by steric hindrance at the site of reaction.
- As primary alkyl halides are less sterically hindered, they undergo SN2 reaction.

* Reactivity towards SN2 reaction of alkyl halides -
1° > 2° > 3°

Hope this helps you...
