2E.25 7th edition

Postby Venya Vaddi 1L » Mon Nov 12, 2018 5:05 pm

In the solutions manual for the 7th edition, the answer to part a 2E.25 is that CH2Cl2 is a polar molecule. Can someone explain why CH2Cl2 is polar? Wouldn't the dipole moments cancel, making this molecule nonpolar?

In CH2Cl2, the 2 C-Cl bonds create a dipole towards the Cl since Cl is highly electronegative. This makes the molecule more negative towards the Cl and away from the 2 H. It is a similar idea to how water is polar with higher negativity towards the oxygen.
