By passing vapours of phenol over heated $zinc$ dust will produce :

What product is formed when phenol reacts with dilute $HNO_3$?

Given below are two statements:
Statement $I$: Phenol on treatment with $CHCl_3 / aq. KOH$ under refluxing condition,followed by acidification produces $p$-hydroxybenzaldehyde as the major product and $o$-hydroxybenzaldehyde as the minor product.
Statement $II$: The mixture of $p$-hydroxybenzaldehyde and $o$-hydroxybenzaldehyde can be easily separated through steam distillation.
In the light of the above statements,choose the correct answer from the options given below:

Which compound does not react with $NaHCO_3$?

Choose the incorrect option based on the reaction:
$(P)$ + $CH_3-CO-Cl \rightarrow (Q)$
Where $(P)$ is salicylic acid and the structure of $(Q)$ is given as:
$(Q)$ is a benzene ring with an $-OH$ group and a $-COO-CO-CH_3$ group at ortho position.

Carbolic acid is oxidised by acidified sodium dichromate to give
