Classification of Elements and Periodicity in Properties

Match the following.

Oxide Nature
(a) CO (i) Basic
(b) BaO (ii) Neutral
(c) Al2O3\mathrm{Al_2O_3} (iii) Acidic
(d) Cl2O7\mathrm{Cl_2O_7} (iv) Amphoteric

Choose the correct option:

  1. A.(a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)
  2. B.(a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)✓
  3. C.(a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
  4. D.(a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
