Answer 1

$A.\to \left(4\right)B.\to \left(1\right)C.\to \left(6\right)D.\to \left(5\right)E.\to \left(3\right)F.\to \left(2\right)$
A. Methanol is also known as 'wood spirit' as it was produced by the destructive distillation of wood.
B. In Kolbe's reaction, 2 - hydroxybenzoic acid (salicylic acid) is prepared by the reaction of phenol with $C{O}_2$ gas.

C. Williamson synthesis is an important method for the preparation of ethers. In this method, an alkyl halide is allowed to react with sodium alkoxide.
R - X + R - ONa $\to$ ROR + NaX
D. When a $2^{\circ }$ alcohol is allowed to pass over heated copper at 573 K, dehydrogenation takes place and a ketone is formed.
$R-\underset{\underset{OH}{|}}{CH}-R^{\prime }\underset{573K}{\overset{Cu}{\to }}R-\underset{\underset{O}{||}}{C}-R$
E. On treating phenol with chloroform in the presence of NaOH, an aldehydic group is introduced at ortho position of the benzene ring

F. Ethanol is prepared by the fermentation of sugars.
$C_{12}{H}_{22}{O}_{11}+H_{2}O\stackrel{Invertase}{\to }{C}_6{H}_{12}{O}_6+C_6{H}_{12}{O}_6{C}_6{H}_{12}{O}_6\stackrel{Zymase}{\to }2C_2{H}_{5}OH+2C{O}_2$
