The product of the following reaction is:

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:

Out of the two compounds shown below,the vapour pressure of $B$ at a particular temperature is expected to be:

Provide the chemical equation for the bromination of anisole.

Assertion : Phenol on oxidation with $KMnO_4$ gives meso-tartaric acid.
Reason : Pure phenol is colourless but turns pink due to oxidation to phenoquinone.

While separating a mixture of $o-$ and $p-$nitrophenols by steam distillation,name the isomer which will be steam volatile. Give reason.
