What is the bond polarity of CH3CL?

In order to determine the bond polarity between two atoms, their respective electronegativities must be determined. is the tendency of a bonded atom to attract bonded electrons to itself. The difference in electronegativity, ##Delta”EN”##, can help predict the bond type.
In general, a ##Delta”EN”## of < 0.4 indicates a nonpolar bond, while a ##Delta"EN"## of 0.4 - 1.7 indicates a polar covalent bond, and a ##Delta”EN”## > 1.7 indicates an ionic bond. https://www.chem.wisc.edu/deptfiles/genchem/sstutorial/Text7/Tx71/tx71.html
For the C-H bond, the ##Delta”EN”## = ##”2.55 – 2.20 = 0.35″##. This is a nonpolar bond because a ##Delta”EN”## of less than 0.4 is indicative of a nonpolar bond.
For the C-Cl bond, the ##Delta”EN”## = ##”|2.55 – 3.16|” = |0.61|”## (##Delta”EN”## is an absolute value; it is never negative.) The ##Delta”EN”## of 0.61 indicates that the C-Cl bond is polar covalent.
