Statement-I : `PCl_(5) "and" PbCl_(4)` are thermally unstable.
Statement-II : They produce same gas on thermal decomposition

Options

A. If both (A) and (R) are true and (R) is the correct explanation of (A)
B. if both (A) and (R) are true but (R) is not correct explanation of (A)
C. If (A) is true but (R) is false
D. If (A) is false but (R) is false

Answer

B, C

Explanation

`PCl_(5)overset(Delta)toPCl_(3)+Cl_(2)`
`PCl_(5)` decomposes into `PCl_(3)` and `Cl_(2)` as in its structure two P-Cl axial bonds are longer than other three P-Cl equatorial bonds.
