JEE Advanced Chemistry question

The thermal stability of hydrides of oxygen family is in order

(A)H2Po < H2Te < H2Se < H2S < H2OCorrect
(B)H2Po < H2O < H2Te < H2Se < H2S
(C)H2S < H2O < H2Te < H2Se < H2Po
(D)H2O < H2S < H2Te < H2Se < H2Po

Answer: (A)

Solution

Going down Group 16, the H–M bond becomes progressively longer and weaker as the central atom grows larger, so the thermal stability of the hydride H2M decreases steadily down the group. Written from least
