प्रश्न
Which halogen compound in the following pair will react faster in SN2 reaction CH3Br or CH3I.
Advertisements
उत्तर
CH3I will react faster in SN2 reaction than CH3Br. This is because I− is a better leaving group, owing to its greater size than Br−. As a result, it will leave at a faster rate in the presence of an incoming nucleophile.
