प्रश्न
Which halogen compound in the following pair will react faster in SN2 reaction CH3Br or CH3I.

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.
