JEE Main levelOne or more correct optionsDifficulty 2 of 3co038

Propan-1-ol can be converted to propanal, without further oxidation to the acid, by

APCC in $CH X_{2} Cl X_{2}$
B $CrO X_{3}$ in aqueous $H X_{2} SO X_{4}$ and acetone (Jones reagent)
Chot acidified $KMnO X_{4}$
Dpassing the vapour over $Cu$ at 573 K

Answer: A, D

PCC and copper-catalysed dehydrogenation stop at the aldehyde. Jones reagent contains water and oxidises the aldehyde hydrate to propanoic acid, and hot

KMnO X_{4}

also gives the acid.
