Chemistry Question on The S-Block Elements
Match List-I with List-II:
| List-I (Oxide) | List-II (Nature) |
|---|---|
| (A) Cl2O7 | (I) Amphoteric |
| (B) Na2O | (II) Basic |
| (C) Al2O3 | (III) Neutral |
| (D) N2O | (IV) Acidic |
Choose the correct answer from the options given below:
A
A-IV, B-III, C-I, D-II
B
A-IV, B-II, C-I, D-III
C
A-II, B-IV, C-III, D-I
D
A-I, B-II, C-III, D-IV
Answer
A-IV, B-II, C-I, D-III
Explanation
Solution
The correct answer is (B) : A-IV, B-II, C-I, D-III
(A) Cl2O7 → Acidic
(B) Na2O → Basic
(C) Al2O3 → Amphoteric
(D) N2O → Neutral
Oxides of metals are basic in nature whereas oxides of non metals are acidic in nature. N2O is a neutral oxide.
