the trigonal bipyramidal structure makes the arrangement as that opposite bonds cancel the dipole moment of each other hence the PCl5 is nonpolar.

Is PCl5 nonpolar or polar?

PCl5 is nonpolar in nature because it has the symmetrical geometrical structure due to which the polarity of P-Cl bonds gets canceled by each other. As a result, the net dipole moment of PCl5 comes out to be zero.

What kind of bond is PCl5?

Phosphorus(V) chloride, PCl

In the case of phosphorus, 5 covalent bonds are possible – as in PCl5. Phosphorus forms two chlorides – PCl3 and PCl5.

So, if a molecule has an electronegativity greater than 2.00 it is ionic (uses ionic bonding), if it is less than 0.50 it is nonpolar (uses nonpolar covalent bonding), and if it is between 0.50-2.00 it is polar (uses polar covalent bonding).
