Question

Match the following

Oxide		Nature
(a)	CO	(ii)	Neutral
(b)	BaO	(i)	Basic
(c)	\(Al_{2}O_{3}\)	(iv)	Amphoteric
(d)	\(Cl_{2}O_{7}\)	(iii)	Acidic

Which of the following is correct option ?

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

Answer 1

The Correct Option is B

To determine the nature of various oxides, we can recall some basic concepts from chemistry related to the types of oxides:

1. Neutral Oxides: These do not react with acids or bases. Carbon monoxide (CO) is a classic example of a neutral oxide.
2. Basic Oxides: These are metal oxides that react with acids to form salts and water. Barium oxide (BaO) is a typical basic oxide due to its metallic character.
3. Amphoteric Oxides: These can react with both acids and bases to form salts and water. Aluminium oxide \((Al_{2}O_{3})\) is amphoteric.
4. Acidic Oxides: These are non-metal oxides that react with bases to form salts and water. Dichlorine heptoxide \((Cl_{2}O_{7})\) is an example of an acidic oxide.

Given the options, let us match each oxide with its nature:

• \((a) \text{ CO} \rightarrow (ii) \text{ Neutral}\)
• \((b) \text{ BaO} \rightarrow (i) \text{ Basic}\)
• \((c) \text{ } Al_{2}O_{3} \rightarrow (iv) \text{ Amphoteric}\)
• \((d) \text{ } Cl_{2}O_{7} \rightarrow (iii) \text{ Acidic}\)

Therefore, the correct matching sequence is:

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

This sequence correctly matches each oxide with its corresponding nature.
