Question

Match List-I with List-II:

List-I (Chemicals)	List-II (Use/Preparation/Constituent)
(a) Alcoholic potassium hydroxide	(i) electrodes in batteries
(b) Pd/BaSO4	(ii) obtained by addition reaction
(c) BHC (Benzene hexachloride)	(iii) used for β-elimination reaction
(d) Polyacetylene	(iv) Lindlar’s Catalyst

Choose the most appropriate match:

• A. (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)
• B. (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)
• C. (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
• D. (a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)

Answer 1

The correct option is D (a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)

Answer: (d)

Alcoholic KOH $\Rightarrow$ Used for beta-elimination reaction due to its strong basic nature.

Pd/ BaSO${}_4$ $\Rightarrow$ Lindlar’s catalyst. It is used for the syn addition of hydrogen to the alkene compound.

BHC (Benzene hexachloride) $\Rightarrow$ Addition product of benzene and chlorine.

Polyacetylene $\Rightarrow$ Highly conducting polyacetylene can be used as an electrode in a solid state cell.
