JEE Main 2026 Apr 2 Shift 2, Chemistry Q8: Group 14 Elements: The Carbon Family

JEE Main2026Apr 2, Shift 2Chemistry

The correct set that contains all kinds (basic, acidic, amphoteric and neutral) of oxides is :

A
Na $_{2}$ O, K $_{2}$ O, Al $_{2}$ O $_{3}$ and As $_{2}$ O $_{3}$
B
Al $_{2}$ O $_{3}$ , As $_{2}$ O $_{3}$ , CO and NO
C
K $_{2}$ O, Cl $_{2}$ O $_{7}$ , As $_{2}$ O $_{3}$ and NO
D
Na $_{2}$ O, N $_{2}$ O, Al $_{2}$ O $_{3}$ and CO

Solution

Classification of common oxides:

Basic: Na $_{2}$ O, K $_{2}$ O (alkali metal oxides).

Acidic: Cl $_{2}$ O $_{7}$ (highest oxide of chlorine).

Amphoteric: Al $_{2}$ O $_{3}$ , As $_{2}$ O $_{3}$ (metalloid/post-transition metal oxides).

Neutral: CO, NO, N $_{2}$ O.

Only option (3) contains exactly one oxide of each kind: K $_{2}$ O (basic), Cl $_{2}$ O $_{7}$ (acidic), As $_{2}$ O $_{3}$ (amphoteric), NO (neutral).
