Condiser the reactions, (i) (CH(3))(2)...

Condiser the reactions,
(i) `(CH_(3))_(2)CH-CH_(2)Broverset(C_(2)H_(5)OH)rarr(CH_(3))_(2)CH-CH_(2)OC_(2)H_(5)+HBr`
(ii) `(CH_(3))_(2)CH-CH_(2)Broverset(C_(2)H_(5)O^(-))rarr(CH_(3))_(2)CH-CH_(2)OC_(2)H_(5)+Br^(-)`
The mechanism of reactions (i) and (ii) are respectively :

A

`S_(N)1 and S_(N)2`

B

`S_(N)1 and S_(N)1`

C

`S_(N)2 and S_(N)2`

D

`S_(N)2 and S_(N)1`

Text Solution

Verified by Experts

The correct Answer is:
C
Since rearrangements do not occur in the given nucleophilic substitution reactions, therefore, carbocations are not the immediates in these reactions. Thus, both the reactions occur by `S_(N)2` mechanism, i.e., option (c) is correct.
