JEE Advanced levelOne or more correct optionsDifficulty 3 of 3co030

Propanone is formed (alone or together with another product) in which of the following?

Apropan-1-ol over $Cu$ at 573 K
Bpropyne with $H X_{2} O$ , $HgSO X_{4}$ , $H X_{2} SO X_{4}$
Cdry distillation of calcium ethanoate
Dreductive ozonolysis of 2-methylbut-2-ene

Answer: B, C, D

Markovnikov hydration of propyne gives propanone. Ozonolysis of

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

gives propanone and ethanal, and

(CH X_{3} COO) X_{2} Ca

gives propanone and

CaCO X_{3}

. Propan-1-ol dehydrogenates to propanal.
