JEE Main levelSingle correct optionDifficulty 2 of 3hc133

2-Methylbut-2-ene is treated with $O X_{3}$ followed by $H X_{2} O X_{2}$ (oxidative work-up). The organic products are

Apropanone and ethanoic acid
Bpropanone and ethanal
Cpropanoic acid and methanal
Dpropanal and ethanoic acid

Answer: A

Cleavage gives

(CH X_{3}) X_{2} C = O

and

CH X_{3} CHO

. A ketone is not oxidised by

H X_{2} O X_{2}

, but the aldehyde is oxidised to

CH X_{3} COOH

.
