प्रश्न
In the following pair of halogen compounds, which compound undergoes a faster SN1 reaction?

Advertisements
उत्तर
The activity of halogen compounds in SN1 reaction depends on the stability of the carbocation formed due to ionization. The order of stability is tertiary > secondary > primary. Hence, 2° alkyl chloride is more active than 1° alkyl chloride. Hence, 2° alkyl chloride is more active in SN1 reaction.
reacts faster due to the greater stability of 2° carbocation than 1° carbocation.
