The C-N bond is a polar bond.
Which is the most polar?
Since nitrogen is one of the most negative elements in the periodic table, the bond it forms with hydrogen will be the most polar out of all those listed. There is a difference in electronegativity between the two atoms that make up a bond.
Which molecule is most polar?
The most polar molecule is water because of the bond between oxygen and hydrogen.
Which is more polar CN or NH?
N-H is the answer.
Why is CN a polar bond?
The large electronegativity difference between the carbon and nitrogen makes them a polar molecule.
