Question

Match the species in Column I with given property (ies) in Column II.

Answer 1

(A) Alkalide of halonium is diamagnetic as all electrons are paired.
Hence, A matches to 2.
(B) Superoxide of alkali metal is paramagnetic due to presence of unpaired electrons. It is used in life saving devices as it can generate oxygen gas through chemical transformation. It is used as an oxidant.
Hence, B matches to 1, 3 and 4.
(C) Peroxide of alkali metal is diamagnetic in nature as all electrons are paired. It is used as an oxidant and bleaching agent.
Hence, C matches to 2,4 and 5.
(D) Oxide of alkali metal is diamagnetic in nature as all electrons are paired. It dissolves Zn and Al metals.

Hence, D matches to 2 and 6.
