Write the order of thermal stability of the hydrides of Group 16 elements

The correct order of thermal stability of hydrides of group 15 is

The correct order of thermal stability of hydrides of group 15 is

The stability of monohalides of group 13 elements

The correct order of thermal stability of hydroxides is :

The increasing order of volatility of hydrides of group 16 elements is -

Thermal stability of hydrides of alkali metals

Thermal stability of hydrides of first group elements follows the order :

Group 16 elements called

Fifth group elements form hydrides to type AH_(3) . The hydrides have a lone pair of electrons. The hydries are reducing in nature and the reducing power is related to the stability of A-H bonds. The hydrides are covalent and low boiling. Their boiling points depends on their ability to from hydrogen bond and their molecular size which decide the intermolcular forces in the hydrides . The boiling points of the hydrides of V-group elements are in the order :

Stability of nitrides of II group elements is in order :
