STANDARD Chemistry Hydrides MCQ Question
Type: MCQ-conceptual-Medium
Which is the correct thermal stability order for H₂E (E = O, S, Se, Te and Po) ?
A
H₂Se < H₂Te < H₂Po < H₂O < H₂S
B
H₂S < H₂O < H₂Se < H₂Te < H₂Po
C
H₂O < H₂S < H₂Se < H₂Te < H₂Po
D
H₂Po < H₂Te < H₂Se < H₂S < H₂O
Correct Answer
Option D
Detailed Explanation
The thermal stability of hydrides decreases down the group. Therefore, the correct order is H₂Po < H₂Te < H₂Se < H₂S < H₂O.
