Yes, PCl5 is a binary molecular compound.
experimental of reaction between pyridine and PCl5
Phosphorus pentachloride is a chemical compound with the formula PCl5.
Valence is the number of bonds to other atoms. It is not always numerically equal to the oxidation number.The valence of phosphorus in PCl3 is 3; of P in PCl5 is 5; of P in H3PO4 is 5 (one of the bonds to oxygen is P=O).
Molar mass = 31+ 5(35.5) = 208.5 g/mole divide ... 35.6 g / 208.5 g/mole = 0.171 mole
maximum of five single covalent bonds as in PCl5
PCL5 is formed two types of P-CL bond, equitorial and axial bonds. The axial bonds suffer more repulsion than the equitorial bonds, and they can easily break, which makes PCL5 unstable. SF6 is largely inert due to steric hindrance.
minimum of three as in NH3, PCl3 maximum of five as in PCl5
The fact that NCl5 does not exist might come into play. Think about it. NCl5 does not exist
PCl5 Phosphorous pentachlorideP for Phosphorous and 5 Cl for chloride= PCl5 College Chemistry student
A pentavalent atom is one that can form 5 chemical bonds, for example nitrogen in HNO3, phosphorus in PCl5.
Three is the answer expected. Higher valences of phosphorus, in PCl5 for example can be explained by hybridisation although this method is not the only explanation.
Phosphorus pentachloride (PCL5)
The name of the compound PCl5 is phosphorus pentachloride.
PCl5 -----> PCl3 + Cl2
