Is Cl2CO a polar or nonpolar molecule? Why or why not?

Answer 1

It's polar because C-Cl and C=O both have dipole moments. While the 2 Cls have dipole moment components that partially cancel each other out, there is a still a difference in dipole moment on the y axis from the y components of the C-Cl and from the C=O bond (if you align the trigonal planar molecule on a cartesian coordinate system.)

Answer 2

It is polar because the eletronegativity difference of Cl and C is 3.0-3.5 = 0.5 > 0.4

Answer 3

polar
b/c of the electronegativity and it is asymmetrical
