Question
The correct order of melting points of hydrides of group 16 elements is: 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 (A) H S < H Se < H Te < H O (B) H O < H S < H Se < H Te (C) H S < H Te < H Se < H O (D) H Se < H S < H Te < H O
Answer: B) H O < H S < H SE < H TE
💡 Solution & Explanation
In general molar mass increases, MP increases but in H O due to H-bonding, it is maximum among the following. Property H O H S H Se H Te m.p. (K) 273 188 208 222
