Consider the reaction :
`CH_(3)CH_(2)CH_(2)Br+NaCNrarrCH_(3)CH_(2)CH_(2)CN+NaBr`
This reaction will be the fastest in :

A

ethanol

B

methanol

C

N, N'-dimethylformamide (DMF)

D

water

Text Solution

Verified by Experts

The correct Answer is:
C
`CH_(3)CH_(2)CH_(2)Br` being a `1^(@)` alkyl halide reacts with `NaCN` by `S_(N)2` mechahnism which is favoured by polar aprotic solvent, i.e., DMF. Thus, option (c) is correct.
