MOLECULAR POLARITYFIELD NOTE 46 / 175
Is C5H5N polar or nonpolar?
Pyridine (C5H5N) is polar because one ring carbon is replaced by nitrogen, breaking benzene's charge symmetry.

Why C5H5N is polar
Pyridine is an aromatic six-membered ring containing one nitrogen. Nitrogen's higher electronegativity creates a distinct ring position and a net molecular dipole.
What to notice
The nitrogen lone pair points outside the aromatic pi system; pyridine can accept a proton without becoming a different carbon framework.
