Question

explain the mechanism of SN1 reaction step by step​

Answer 1

Answer:

SN1 reaction mechanism follows a step by step process wherein first, the carbocation is formed from the removal of the leaving group. Then the carbocation is attacked by the nucleophile. Finally, the deprotonation of the protonated nucleophile takes place to give the required product. The rate determining step of this reaction depends purely on the electrophilicity of the leaving group and is not impacted at all by the nucleophile.

Answer 2

Answer:

As name indicates,it is a first order reaction

i.e,rate of reaction depends upon the concentration of substrate only,not upon the concentration of nucleophile....

this reaction occurs in 2 step

Step 1:

• there is heterolytic cleavage of C-X bond to generate a carbonium ion which is a planar species(i.e,carbonium ion carbon is in sp2 hybridized state)
• this is a slow step,hence it is rate determining step...

Step 2:

• nucleophile attacks on carbocation to give the substituted product immediately as carbocation is highly reactive species.
• this is a fast step, hence it doesn't affect the rate of reaction...

During the SN1 reaction optically active reactant will give optically inactive product...

☞Note:

All tertiary alkyl halides undergo SN1 reaction...

plzzz refr the pic attached too...

hope this helps u ✌️☺️
