Why is BrCl5 nonpolar when it's Asymmetrical? Aren't symmetrical molecules suppposed to be polar?

BrCl₅ is an asymmetrical molecule because it has one lone pair and five atoms bonded to the central atom. Due to low difference of electronegativities, BrCl₅ is a nonpolar molecule.

Explanation:

According to the Linus Pauling scale, the difference between their electronegativities Δx can be determined if the link will be:

polar: 0 ≤ Δx ≤ 0.4

nonpolar: 0.5 ≤ Δx ≤ 1.6

ionic: 1.7 ≤ Δx ≤ 2.0

Br-Cl bonds are nonpolar because the difference between their electronegativities is:

Br: 2.96

Cl: 3.16

Δx= 3.16 - 2.96 = 0.2

BrCl₅ has nonpolar bonds.

BrCl₅ is non-polar as

BrCl₅ is an asymmetrical molecule, the bromine is present in the center and five chlorine are present around the bromine atoms. This will form a square pyramidal structure and the intermolecular forces present are the dispersion forces.

Due to low difference of electronegativities, BrCl₅ is a nonpolar molecule.
Br-Cl bonds are nonpolar because the difference between their electronegativities is: Br: 2.96 , Cl: 3.16
Δx= 3.16 - 2.96 = 0.2
BrCl₅ has nonpolar bonds.
