(1) For IV A group elementsCommon oxidation state is : "+4"C shows :- +4 , -4Si:- +4 [Stable]Ge,Sn - +2, +4Stable Pb: - +2Stable +4→ For Ge,Sn +4 is stable oxidation state hence in +2 oxidation state they acts as reducing agents→ Where as for Pb '+2' oxidation state is stable [due to inert pair effect] hence in +4 oxidation state Pb acts as oxidising agent→ Higher oxidation state is due to involvement of ns and np electronsi.e., Lower oxidation state is due to involvent of only np electroni.e., ns2 np(2) ⇒ +2Higher oxidation state stability dcecreases from top to bottomGe+4>Sn+4>Pb+4 Stability order Ge+4
