Question

In each of the following pairs indentify the compound which will undergo sn1 reaction.

Answer 1

In sn1 reaction, a carbocation as an intermediate is formed and a tertiary carbocation is most stable one.

Therefore, Tertiary compounds (3°) undergo sn1 reaction very readily

Priority sequence: 3°>2°>1°

(a) compound 1 will undergo sn1 reaction since Cl is attached to 3° carbon

(b) compound 1 will undergo sn1 reaction, coz Cl is attached to 2° carbon

Hope u understand.
