Statement-I: All P-CI bonds in PCI5 are equal in length.Statement-II: In vapour state PCl5 (PCI4)+ (PCI6)– .

Both (A) and, (R) are false. PCl5 exists as (PCl4)+ (PCl6)– in solid state. in vapour form it exists as trigonal bipyramidal molecule with two axial P-Cl bonds equal in length and larger than other three equatorial P—Cl bonds.
