Question

Is BrCl5 polar?

Answer 1

BrCl5 has 6 effective pairs around the central Br atom, 5 of which are Br-Cl bonds, while 1 is a lone pair. Since all 6 aren't the same and because the bond dipoles don't all cancel each other out, BrCl5 must be polar.

Answer 2

It's polar because of the lone pair in the lewis dot structure

Answer 3

I would say that that compound is non-polar. The condition for a compound to be polar is that the two bonded atoms should a minimum electronegative difference of 4. Cl has an electronegativity od 3.9 and Br 2.8, their difference is 0.2, hence non-polar.

Answer 4

@Hoslos Yes the \(\sf Br-Cl\) bond is non-polar. But \(\sf Br\) has an lone pair of electrons.

Answer 5

Yes, but having a lone pair does not necessarily determine wether or not the molecule is polar or non-polar.
