Question

What is SN² and SN¹ mechanism.​

Answer 1

Answer:

SN¹ mechanism:

The SN¹ reactor is a substitution reaction in organic chemistry. Stands for nucleophilic substitution.

SN² mechanism are bimolecular in rate of reaction and have a concerted mechanism and SN¹ is unimolecular in the rate of reaction.

Answer 2

SN1 and SN2 are necleophellic reaction in which :-

SN1 :--- it is a type of nucleophilic reaction.Which is faster then SN1 and the attacking of nuclophile suffered from two type of restriction

• Size of atom is larger .
• the nuclophile doesn't attack due to stability like resonance

This reaction is in of 1 process only in which nuclophile attack and form a bond with them

the site for nucleophile attack in hybridition in order

sp3>sp2>sp1

SN2 :---> it is also called nuclophile reaction.This reaction involve in 2 steps first is slow called rate determining steps and 2nd is fast .

the overall reaction is slower then SN1

favourable site to attack in hybridisation in order

Sp1>sp2>>sp3
