X Y
A. liquid sodium metal I breathing apparatus in submarine
B. potassium stearate II explosive
C. potassium nitrate III coolant in nuclear reaction
D. potassium superoxide IV soft soap
Options
A.A → I, B → III, C → II, D → IV
B.A → III, B → IV, C → II, D → I
C.A → II, B → I, C → III, D → IV
D.A → IV, B → II, C → III, D → I
Solution
(A) Liquid sodium metal is used as coolant in nuclear reaction.
(B) Steric acid is CH3(CH2)16 COOH and potassium stearate is CH3(CH2)16 COOK which is used in the preparation of soft soaps.
(C) Potassium nitrate is used in gun powder as explosive.
(D) Potassium superoxide absorbs CO and CO2 and liberates oxygen gas. Therefore it is used in breathing apparatus in submarine.
