Toluene $\xrightarrow[{heat}]{{NBS\,/\,CCl_4}} A$ $\xrightarrow{{CH_3ONa}} B,$
The final product $(B)$ formed in the reaction sequence is:

$A$ bromoalkane $X$ reacts with magnesium in dry ether to form compound $Y$. The reaction of $Y$ with methanal followed by hydrolysis yields an alcohol having molecular formula $C_{4}H_{10}O$. The compound $X$ is

What is the product formed when chloroform reacts with concentrated $HNO_3$?

In the given pairs of alkyl halides,in which pair is the first compound more reactive than the second compound toward $S_N2$ reaction?

$S_N1$ reactions are generally carried out in which type of solvents?

The reaction of $4-methylcyclohexyl$ halide with $OH^-$ via the $S_N2$ mechanism produces $A$. Identify $A$.
