The reactivity alkyl halides depends the nature the leaving group
Solution answers
In an sn2 reaction, the reactivity of alkyl halides depends on the nature of the leaving group, with better leaving groups being more reactive. In Problem 22, we can compare the reactivity of alkyl halides in an SN2reaction with a given nucleophile:
a. CH<sub>3</sub>CH<sub>2</sub>CH<sub>2</sub>Br or CH<sub>3</sub>CH<sub>2</sub>CH<sub>2</sub>I: In this case, CH<sub>3</sub>CH<sub>2</sub>CH<sub>2</sub>I would be more reactive in an SN2reaction. Iodide (I-) is a better leaving group than bromide (Br-).
f. CH<sub>2</sub>CH=CCH<sub>3</sub> or CH<sub>3</sub>CH=CHCH<sub>3</sub>: CH<sub>3</sub>CH=CHCH<sub>3</sub> would be more reactive in an SN2reaction. The presence of the double bond in CH<sub>2</sub>CH=CCH<sub>3</sub> hinders the approach of the nucleophile in an SN2reaction.
In Problem 23, we need to identify which compound would be more reactive in an SN1 reaction. However, the problem statement seems to contain a typo as it mentions "SN1" instead of "SN1." Could you please clarify?
