Bcl3 Polar Or Nonpolar
Is BCL3 polar or non-polar? ۔
Triangular plane, 120 degree connection angle.
The BCl3 molecule is known as the flat triangle. This means that there is 120 views between each link. The easiest way to see why it's non-polar with a vector. When I am at one end of the Cl bond, add the other two bonds from the end as tail vectors, they will stand in a triangle. Therefore, the charge will not work in the right direction and therefore the molecule is non-polar. It's hard to explain what I find useful!
Although the electronegativity difference between boron and chlorine is less than 1.4, the fact that all bonds are equal negates the change in polarity.
It's not just the difference in electronity (which is only 1), it's the geometry of the VSEPR molecule.
