Polar/Nonpolar

Postby Jonathan Pai 2I » Sun Nov 18, 2018 9:50 pm

Why is CH2Cl2 polar, I was thinking them H's would cancel each other and them Cl's would cancel each other. This problem 2E25D.

Thanks CC squad!

I think the shape of ch2cl2 is tetrahedral. So the chlorine atoms are 109.5 degrees away from each other and not opposite from each other. This means theres a dipole moment which don't cancel. Hope this helped.

In CH2Cl2, the 2 bonds create a dipole towards the Cl since it is electronegative. This makes the molecule negative towards the Cl and away from the 2 H.

Although the bond arrangement around the C atom is symmetrical the different polarities of the C-Cl and C-H bonds means the effects of the bonds aren't canceled.
