Solution
The correct option is D Propan-2-ol
Propan-2-ol would be oxidised to propan-2-one.
CH3−CH|OH−CH3oxidation−−−−−−−−→CH3−C||O−CH3
Ethanol (CH3−CH2−OH) would
be oxidised to ethanal (CH3−C||O−H) . Butan-1-ol (CH3−CH2−CH2−CH2−OH) would be oxidised to Butanal (CH3−CH2−CH2−C||O−H).
2-methylpropan-2-ol (CH3−C|OH(CH3)−CH3) is a tertiary alcohol and requires drastic conditions
for its oxidation. The number of C atoms in oxidation product of
2-methylpropan-2-ol will be less than the number of C atoms in
2-methylpropan-2-ol.
