Why pf5 exists but ph5 donot exists

1.	Why pf5 exists but ph5 donot exists
Answer» PF5 EXISTS but PH5 does not because of the FOLLOWING reasons - H is smaller in size than F PH5 is formed by the overlap of d orbitals with Sp3d HYBRIDISATION. F is more electronegative so Sp3d hybridisation is possible but H has LESSER electronegativity and can not form sp3d hybridization and PH5 cannot be formed.

PF5 EXISTS but PH5 does not because of the FOLLOWING reasons -

H is smaller in size than F

PH5 is formed by the overlap of d orbitals with Sp3d HYBRIDISATION.

F is more electronegative so Sp3d hybridisation is possible but H has LESSER electronegativity and can not form sp3d hybridization and PH5 cannot be formed.
