Answer #1

Ans :

When the nucleophilic substitution reactions are carried , the -OH group of the alcohol behaves as a poor leaving group , due to which it is difficult to remove the group from the alcohol.

When the reactions are performed in the acidic conditions , the alcohol gets protonated by the acid , and its -OH group (poor leaving group) changes into H2O (good leaving group).

So the leaving group leaves the compound easily and the reactions are performed easily , and hence the competing nucleophile reactions are carried out under acidic conditions.

Most reactions that can be done under acidic conditions can also be done under basic conditions – for example, conversion of a ketone into a ketal. That said, the reason Fischer esterifications require acid catalysis is that protonating the acid makes the electrophile (the carbonyl carbon) a better electrophile. We could presumably make the nucleophile (an alcohol) a better nucleophile, which is usually done through deprotonation. Explain why reacting an alkoxide with a carboxylic acid will not result in a...
