The correct order of acidic character of group- 16 hydrides is
Options
- AH ₂ O < H ₂ ~S < H ₂ Se < H ₂ Te
- BH ₂ O > H ₂ ~S > H ₂ Se > H ₂ Te
- CH ₂ O H ₂ Se > H ₂ Te
- DH ₂ O H ₂ Te
Correct answer
A. H ₂ O < H ₂ ~S < H ₂ Se < H ₂ Te
Step-by-step solution
Acidic character increases down the group as the M- H bond strength decreases. Hence, the correct option is (1).
