Why is CH3Cl polar?

It is polar because it has 3 C-H bonds and 1 C-Cl bond, so when you find the difference of the electronegativity values (C)2.55-(H)2.20=0.35 and (Cl)3.16-(C)2.55=0.61. So one of the arrows for the polarity points towards Chlorine, and the other three point towards Carbon from the 3 Hydrogens. The Lewis structure looks like this:

..

:Cl:

l

H - C - H

l

H

So here's the thing, the Cl is more negative than the C because the Cl has a higher electronegativity charge. And the C is more negative compared with the H because the C has a higher electronegativity charge than the H's. Therefore it is polar which means it has exposed ends (in this case the H's and Cl) with opposite partial charges.

Each C-H bond is polar since carbon is more electronegative than hydrogen, and the C-Cl bond is polar since chlorine is more electronegative than either carbon or hydrogen. Each hydrogen atom will take on a partial positive charge, and the chlorine atom will take on a partial negative charge resulting in a net dipole since the dipoles will not cancel out owing to the difference in the electronegativities of carbon, hydrogen and chlorine.

CH3Cl is a fairly polar molecule. The C-Cl bond has a large difference in electronegativity compared to the H-C bonds. Cl is one of the more electronegative elements.

CH3Cl is always polar. CH3Cl is a fairly polar molecule. The C-Cl bond has a large difference in electronegativity compared to the H-C bonds. Cl is one of the more electronegative elements.
