Phos… Phosphorus can form PCl 5 since it has vacant d-orbitals in its valence shell. 09. The first one is the large radius for I, which doesn’t allow to place five Iodine around phosphorus at proper distances. PCl5 is a water-sensitive… ( candiedsparkle are you missexclusive ?, let her answer)​. Since phosphorus has no vacant d-orbitals; hence overlapping of 5 atoms of either bromine or iodine is not possible to fit into them.Also the size of phosphorus atom is smaller than that of Bromine and Iodine thus a single Phosphorus atom cannot contain or hold 5 halogens Br or I atoms together. 8.Why all the five bonds in PCl5 are not equivalent? 3 Throwing a die.
