Cumyl chloride reacts with azide ion in water to form a mixture of an alcohol and an alkyl azide. Predict the effects of each change listed below on (i) the overall rate of reaction and (ii) the relative amounts of products A and B. If the effects are small, you can just say "little effect."

Lillian Salazar · Answer 1

(a). Increase in the rate of Reaction.

(b). Increase in the formation of the alcohol.

(c). rate of Reaction will increase that is to say more of the alkyl azide will be produced.

(d). rate of Reaction will increase that is to say more of the alkyl azide will be produced.

(e). rate of reaction increases because of carbocation.

Explanation:

Important thing to note is that this reaction proceed with an SN1 mechanism.

Therefore; the rate of reaction depends solely on the concentration of alkyl azide.

(a). The concentration of the alkyl chloride is increased: rate of Reaction will increase that is to say more of the alkyl azide will be produced.

(b) The concentration of the azide ion is increased: the effect is that there will be an increase in the formation of more of the alcohol.

c) The alkyl bromide is used instead of the alkyl chloride: the effect is that there will be rate of Reaction will increase that is to say more of the alkyl azide will be produced.

(d) The reaction is carried out in 1:1 acetone water instead of pure water: the effect is that there will be the effect is that there will be rate of Reaction will increase that is to say more of the alkyl azide will be produced.

(e) The alkyl chloride shown below is used instead of cumyl chloride: rate of reaction increases because of carbocation.
