Consider the reaction

CH3CH2CH2Br+NaCN→CH3CH2CH2CN+NaBr

This reaction will be the fastest inNEET 2016 (Phase 2)

Options:

Answer:
C
Solution:

The reaction proceeds viaSN2mechanism. It is a unimolecular nucleophilic substitution reaction. The reaction is hence favoured in the presence of a polar aprotic solvent. DMF is a polar aprotic solvent. So, the reaction is the fastest with DMF solvent.
