Consider the reaction CH(3)CH(2)CH(2)B...

Consider the reaction
`CH_(3)CH_(2)CH_(2)Br+NaCN to CH_(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
The given reaction follows `S_(N)2` mechanism and `S_(N)2` reactions are favoured in polar aprotic medium like DMSO, DMF.. Etc.
`CH_(3)CH_(2)CH_(2)Br+NaCN overset(DMF)to CH_(3)CH_(2)CH_(2)CN+NaBr`
So, the correct option is (c ).
