Answer 1

Answer:

Drago's rule is an empirical rule and is used to explain the bond angles of hydrides of group 15 and 16 of or below 3rd period. So essentially it is only applicable for PH3, AsH3,SbH3 and H2S, H2Se, H2Te.The inert-pair effect is the tendency of the two electrons in the outermost atomic s-orbital to remain unshared in compounds of post-transition metals. ... As a result, the inert pair of ns electrons remains more tightly held by the nucleus and hence participates less in bond formation.
