Which of the following is $NOT$ produced by the reaction of ethanol with $H_2SO_4$?

The product $\begin{array}{*{20}{c}} {CH_2 - O - COCH_3} \\ {|} \\ {CH_2 - O - COCH_3} \end{array}$ is obtained by the reaction of which of the following?

An organic compound $(A)$ reacts with sodium metal to form $(B)$. When $(A)$ is heated with concentrated $H_2SO_4$,it produces diethyl ether. What are $(A)$ and $(B)$ respectively?

$PCl_5$ reacts with a compound containing

$8.8 \ g$ of monohydric alcohol added to ethyl magnesium iodide in ether liberates $2240 \ cm^3$ of ethane at $STP$. This monohydric alcohol when oxidized using pyridinium chlorochromate $(PCC)$,forms a carbonyl compound that answers the silver mirror test (Tollen's test). The monohydric alcohol is:
