NEET levelSingle correct optionDifficulty 1 of 3ap058

Vapours of propan-2-ol are passed over hot copper at 573 K. The product is

Apropene
Bpropan-1-ol
Cpropanal
Dpropanone

Answer: D

Hot copper at 573 K dehydrogenates primary alcohols to aldehydes and secondary alcohols to ketones. Propan-2-ol is secondary, so it loses

H X_{2}

to give

CH X_{3} COCH X_{3}

, propanone.
