Question

Match the following, regarding nature of the oxides.

Column -I	Column-II
a. $N_{2}O$	(i) Basic
b. BaO	(ii) Amphoteric
c. $A{s}_2{O}_3$	(iii) Acidic
d. $C{l}_2{O}_7$	(iv) Neutral

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

Answer 1

Answer: (C)

a(iv), b(i), c(ii), d(iii)

(A) $N_{2}O⟶$ (iv) Neutral as it neither shows properties of a base nor acid.

(B) $BaO⟶$ (i) Basic; Metallic oxides are basic oxides.

(C) $A{s}_2{O}_3⟶$ (ii) Amphoteric as it can act both as a base and an acid.

(D) $C{l}_2{O}_7⟶$ (iii) Acidic as non-metallic oxides are acidic in nature.
