In case of nitrogen, `NCl_(3)` is possible but not `NCl_(5)` while in case phosphrous, `PCl_(3)` as well as `PCl_(5)` are possible. It is due to

A

Availability of vacant d orbitals in P but not in N

B

Lower electronegativity of P than N

C

Lower tendency of H-bond formation in P than N

In gas phase, all P-Cl bonds of PCl_(5) have same bond length. IV.

(A) PCl_(5) is more covalent than PCl_(3) (R ) Polarising power of P^(5+) is greater than that of P^(3+)

Those stereoisomers are called configurational isomers if they differ in spatial arrangement of atom or group and are not interconvertible without cleaving a bond. Geometrical isomer arises due to restricted rotation about a bond or centre. The number of G.I is 2^(n) where n= number of stereoisomers, in some cases the number of G.I is less than 2^(n) in case where either side nomenclature will be possible. The number of G.I. of the compound C_(2)H_(5)-CH=CH-CH=CH-CH=CH-CH_(3) is
