Question

•●○°reactivity of alcohols towards nucleophilic addition reactions_?​

Answer 1

Answer:

when electron withdrawing bromo or nitro group is present as a substituent in para position . the reactivity of alcohol towards nucleophilic substituted HBr is decreased

Answer 2

Explanation:

write an equation to illustrate the formation of acetals.

identify the acetal formed from the reaction of a given aldehyde or ketone with a given alcohol.

identify the carbonyl compound, the alcohol, or both, needed to form a given acetal.

write a detailed mechanism for the reaction which occurs between an aldehyde or a ketone and an alcohol.

explain how an acid catalyst makes aldehydes and ketones more susceptible to attack by alcohols.

illustrate how the reversibility of the reaction between an aldehyde or a ketone and an alcohol can be used to protect a carbonyl group during an organic synthesis.
