Question

Comment on the stability of order of H2E , where E is group 16 elements.

Answer 1

$\huge{\mathfrak{HEYA\:MATE\:!!}}$

Answer....

The thermal stability decreases down the group.

This is so because, on going down the group, the size of the elements increases. As the size increases, less energy is required to break the bonds and dissociation takes place easily.
