Which of the following statement is/are correct ?

Options

A. Phenol is more easily oxidised than benzene.
B. Benzaldehyde and PhCI can be distiguished by `NaHSO_(3)`.
C. p-Cresol and benzoic acid can be distinguished by NaOH.
D. Phenol and benzoic acid can be distiguished by adding dry in aqueous NaOH solution.

Answer

A, B, D

Explanation

a. The `bar e`-donating effect of (OH) makes the ring of phenol very `bar e`-rich, enabling it to readily donate `bar e`'s to oxidising agents.
b. Benzaldeyde reacts with `NaHSO_(3)` but PhCI does not.
c. Both react with NaOH to form sodium salts.
d. Dry ice `(CO_(2))` reacts with aq. NaOH to form `NaHCO_(3)`, which reacts with acid to form `PhCOONa+CO_(2)+H_(2)O` .
