Acetaldehyde reacts with

Answer»

Electrophiles only
Nucleophiles only
Free radicals only
Both electrophiles and nucleophiles

Solution :Acetaldehyde reacts only with nucleophiles. Since the MOBILE p-electrons of carbon-oxygen double bond are STRONGLY pulled TOWARDS oxygen, carbonyl carbon is electron-deficient and carbonyl oxygen is electron-RICH. The electron deficient (acidic) carbonyl carbon is most susceptible to attack by electron rich nucleophilic reagents, that is, by base. Hence the typical reaction of aldehydes and ketones is nucleophilic addition.
