Match List - I with List - II : List - I (Chemicals) List - II (Use / Preparation / Constituent) (a) Alcoholic potassium hydroxide (i) Electrodes in batteries (b) Pd / BaSO 4 (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

Options

  1. Aa − ii , b − i , c − iv , d − iii
  2. Ba − iii , b − iv , c − ii , d − i
  3. C  a - iii , b − i , c − iv , d − ii
  4. Da − ii , b − iv , c − i , d − iii

Correct answer

B. a − iii , b − iv , c − ii , d − i

Step-by-step solution

(a) Alcoholic potassium hydroxide → used for β - elimination (b) Pd / BaSO 4 → Lindlar's catalyst (c) BHC (Benzene hexachloride) → Obtained by addition reactions (d) Polyacetylene → Electrodes in batteries
