Question

Write the order of thermal stability of the hydrides of group-16 elements.

Answer 1

Answer:

Thermal stability of hydrides of group 16 decreases from H2O to H2PO.

H2O > H2S > H2SE > H2Te > H2PO.

Answer 2

Answer:

The thermal stability of the hydrides of group 16 elements decreases down the group,

i.e., H2O > H2S > H2Se > H2Te > H2Po.
