Solution:

The correct matches of pair are as follows A-III, B-I, C-IV, D-II.

(A) Methanol

(\mathrm{CH}_3\mathrm{OH})

, also called methyl alcohol, wood alcohol, or wood spirit is the simplest of a long series of organic compounds called alcohols, consisting of a methyl group

(\mathrm{CH}_3)

linked with a hydroxy group

(\mathrm{OH})

. Methanol was formerly produced by the destructive distillation of wood.

(B) Lucas reagent is a solution of anhydrous zinc chloride in concentrated hydrochloric acid. This solution is used to classify alcohols of low molecular weight. The reaction is a substitution reaction in which the chloride replaces a hydroxyl group.

\mathrm{C}_2\mathrm{H}_5\mathrm{OH}

. Ethanol with

95\%

purity is called rectified spirit. It contains

95.57\%

ethyl alcohol and

4.43\%

water. In other words it can be said that rectified spirit is highly concentrated ethanol.

(D) Baeyer's reagent is a very cold dilute solution of alkaline potassium permanganate. It is a purple or light violet coloured solution. Baeyer's reagent is a strong oxidising reagent which is used to identify the presence of double or triple bonds in a hydrocarbon.
