MOLECULAR POLARITYFIELD NOTE 100 / 175
Is Cyanogen (C2N2) polar or nonpolar?
Cyanogen (C2N2) is nonpolar because its matching terminal nitrogen atoms lie at opposite ends of a straight molecule.

Why C2N2 is nonpolar
Cyanogen has the connectivity N≡C–C≡N. Both nitrile ends pull charge in equal but opposite directions along one line. The molecule therefore has no net permanent dipole despite the polar C≡N bonds.
What to notice
HCN and cyanogen both contain a C≡N group. HCN has unlike ends and is polar; cyanogen has matching N≡C ends and cancels its two bond contributions.
Common questions about C2N2
