Which statements about PCC in $CH X_{2} Cl X_{2}$ are correct?

APentan-1-ol is oxidised to pentanal.
BCyclohexanol is oxidised to cyclohexanone.
CBenzyl alcohol is oxidised to benzoic acid.
D2-Methylpropan-2-ol is not oxidised.

Answer: A, B, D

PCC oxidises primary alcohols to aldehydes and secondary alcohols to ketones, so (A) and (B) are right and (C) is wrong because the oxidation stops at benzaldehyde. A tertiary alcohol has no C-H on the carbinol carbon and is not oxidised, so (D) is right.
