प्रश्न
Which would undergo SN2 reaction faster in the following pair and why ?
Advertisements
उत्तर
Primary alkyl halides prefer to undergo SN2 reactions than tertiary alkyl halides because of less steric hindrance experienced by the approaching nucleophile. Hence, out of the given pair (CH3−CH2−Br) would undergo SN2 reaction faster.
