MOLECULAR POLARITYFIELD NOTE 103 / 175
Is Ethanethiol (C2H6S) polar or nonpolar?
Ethanethiol (C2H6S) is polar because the sulfur-bearing –SH end differs from its two-carbon hydrocarbon end.

Why C2H6S is polar
Ethanethiol has a CH3–CH2–S–H chain. Sulfur keeps two lone pairs and makes a bent local arrangement with C and H. The sulfur-containing end and the hydrocarbon end have different electron distributions, giving a net dipole.
What to notice
Ethanethiol and dimethyl sulfide share the formula C2H6S. One has an S–H bond; the other puts sulfur between two methyl groups, so their Lewis structures must not be merged.
