JEE Main levelSingle correct optionDifficulty 2 of 3hc040

2-Methylbut-2-ene is ozonised and the ozonide is worked up with $H X_{2} O X_{2}$ (oxidative work-up). The products are

Apropanone and ethanal
Bpropanal and ethanoic acid
Cpropanone and ethanoic acid
Dbutanone and methanoic acid

Answer: C

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

is cleaved into

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

(a ketone, unchanged) and

CH X_{3} CHO

. Hydrogen peroxide oxidises the aldehyde to

CH X_{3} COOH

.
