Choose the correct statement regarding `PCl_(5)`

Options

A. In solid phase, hybridisation of P-atom in cation is `sp^(3)`
B. In vapour phase, al P-Cl bond lengths are equal
C. In vapour and solid phase, central atom has no lone pair
D. In solid phase, anion has only one type of bond angle

Answer

A, C

Explanation

In gaseous or vapour phase `PCl_(5)` exists as discrete molecule.

whereas in solid state it exists as `[PCl_(4)]^(+)[PCl_(6)]^(-)`
