What are alcoholic beverages made of?

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?

Explain the types of reactions given by alcohol compounds with examples.

Match the reagents in Column-$I$ with the major products obtained from the reaction of $Butan-1-ol$ in Column-$II$.

Column-$I$ (Reagents)	Column-$II$ (Products)
$A$. $HCl + ZnCl_2$	$i$. $CH_3CH=CHCH_3$
$B$. $HBr$	$ii$. $CH_3CH_2CH_2CH_2Cl$
$C$. $SOCl_2$	$iii$. $CH_3CH_2CH_2CH_2Br$
$D$. $H_2SO_4, \Delta$	$iv$. $CH_3CH_2CH_2CH_2Cl$

$0.44 \ g$ of a monohydric alcohol when added to methylmagnesium iodide in ether liberates $112 \ cm^{3}$ of methane at $S.T.P.$ With $PCC$,the same alcohol forms a carbonyl compound that answers the silver mirror test. The monohydric alcohol is:

The compound which will give a negative iodoform test is
