MolSynapse / Question bank / Alcohols, Phenols and Ethers / Reactions of alcohols: oxidation, esterification, dehydration, Lucas test

NEET levelSingle correct optionDifficulty 1 of 3ap057

Ethanol is treated with $PCC$ in $CH X_{2} Cl X_{2}$ . The main organic product is

Aethanoic acid
Bethanal
Cethyl ethanoate
Dethene

Answer: B

PCC

in anhydrous

CH X_{2} Cl X_{2}

is a mild oxidant that stops at the aldehyde stage because no water is present to form the aldehyde hydrate. Hence

CH X_{3} CH X_{2} OH

gives

CH X_{3} CHO

(ethanal) and not the acid.
