The heavier members of `13` and `14` groups besides the group oxidation state also show another oxidation state. Down the group `(darr)`, the stability of higher oxidation state increases. This concept which is commonly called inert pair effect has been used to explain many physical and chemical properties of the element of these groups.

1.	The heavier members of `13` and `14` groups besides the group oxidation state also show another oxidation state. Down the group `(darr)`, the stability of higher oxidation state increases. This concept which is commonly called inert pair effect has been used to explain many physical and chemical properties of the element of these groups. Heavier members of group `13` exhibit oxidation state.A. `+3` onlyB. ` +1` onlyC. `+1` and `+ 3` bothD. `+1,+2, +3`
Answer» Correct Answer - C Due to the inert pair effect, heavier members of group `13` exhibit `+3` (group oxidation state) and `+1` oxidation states.
