Question
Look at the following electrostatic potential map of methylamine, a substance responsible for the odor of rotting fish, and tell the direction of polarization of the C-N bond:
Step-by-Step Solution
VerifiedIn an electrostatic potential map, the color red indicates regions of a molecule that are electron rich. The map shows the nitrogen is most electronegative atom in methylamine, and the direction of polarity of C-N bond is towards nitrogen.
Polarity is a separation of electric charge leading to a molecule or its chemical group having an electric dipole moment, with a negatively charged and positively charged end. Polar molecules must contain one or more polar bonds due to difference in electronegativity between the bonded atoms. It also occurs when two atom do not share electron equally in covalent bond.
Electronegativity is a chemical property that describes the tendency of an atom or functional group to attract electron toward itself.it is dimensionless property because it is only a tendency.
A nitrogen is more electronegative element than carbon the electron density of C-N bond will be shifted towards nitro.

Direction of polarization of C-N bond in Methylamine
Methylamine contains an electronegative nitrogen atom with a lone pair of electrons. The dipole moment thus points generally from CH3 toward the
lone pair.
