Answer 1

Answer: (C)

$\left(A\right)\to \left(iv\right),\left(B\right)\to \left(i\right),\left(C\right)\to \left(vi\right),\left(D\right)\to \left(v\right),\left(E\right)\to \left(iii\right),\left(F\right)\to \left(ii\right)$

A. Methanol is also known as the wood spirit because it can be produced as a by-product of the wood distillation

B. Kolbe's reaction is the conversion of phenol to salicylic acid (o-hydroxybenzoic acid) by the action of carbon dioxide in an alkaline medium as:

$C_6{H}_{5}OH+C{O}_2+aq.NaOH\to o-\left(COOH\right)C_6{H}_{4}OH$

C. Williamson's synthesis is a reaction for ether synthesis from an alkyl halide and sodium alkoxide reaction.

D. Conversion of $1^{\circ }$ alcohol to aldehyde can be done by passing over $Cu$ at high temperature i.e. 573 K.

E. Reimer-Tiemann reaction is the conversion of phenol to salicylaldehyde (o-hydroxybenzaldehyde) by the action of chloroform/trichloromethane in an alkaline medium as:

$C_6{H}_{5}OH+CHC{l}_3+aq.NaOH\to o-\left(CHO\right)C_6{H}_{4}OH$

F. Fermentation of glucose by Zymase gives ethyl alcohol as the product
