1.	Statement-I : `PCl_(5) "and" PbCl_(4)` are thermally unstable. Statement-II : They produce same gas on thermal decompositionA. If both statement -I & Statement-II are true & the Statement-II is correct explaination of the statement-I.B. If both Statement-I & Statement-II are true but Statement-II is not a correct explainatin of Statement-I.C. If Statement-I is True but the Statement-II is FalseD. If the Statement-I is False but the Statement-II is True
Answer» Correct Answer - B `PCl_(5)overset(triangle)toPCl_(3)+Cl_(2)` `PCl_(5) "decomposes into" PCl_(3) "&" Cl_(2)` as in its structure two `P-Cl` axial bonds are longer than other three `p-Cl` equatorial bonds. `PbCl_(4)overset(triangle)toPbCl_(2)+Cl_(2)` Due to inert pair effect, `Pb^(4+)` is unstable therefore it changes into more stable `Pb^(++)`

The heavier elements of groups 13 and 14 besides the group oxidation state exhibit another oxidation state which is two units lower than the group oxidation state and the stability of this lower oxidation state increases down the group. 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. Element of group 13A. exhibit oxidation state of `+3` onlyB. form `M^(+)` and `M^(3+)` ionsC. exhibit oxidation states of +1 and +3D. form `M^(-)` and `M^(+)` ions
