Phenol reacts with acetone in the presence of concentrated sulphuric acid to form a $C_{15}H_{16}O_2$ product. Which of the following compounds is this product?

The action of diazomethane on phenol liberates which of the following gases?

The order of stability of the conjugate base of the given acids is:
$(i)$ Phenol
(ii) $4-$Hydroxypyridine
(iii) Cyclohexanol

Assertion $(A)$: Chlorobenzene is not formed in the reaction of phenol with thionyl chloride.
Reason $(R)$: In phenol,the carbon-oxygen bond has partial double bond character.
The correct answer is

Which among the following phenols does $NOT$ correctly match with their $IUPAC$ names?

Given below are two statements:
Statement $I$: Bromination of phenol in solvent with low polarity such as $CHCl_3$ or $CS_2$ requires Lewis acid catalyst.
Statement $II$: The Lewis acid catalyst polarises the bromine to generate $Br^{+}$.
In the light of the above statements,choose the correct answer from the options given below:
