which functional group is more electronegative, amine C-NH, or alcohol C-OH, in assigning carbon environment?

The correct answer is: alcohol (C-OH) functional group

Explanation:

Electronegativity is described as the ability or the tendency of an element to attract the electron density or shared bonding electrons towards itself.

The electronegativity value of oxygen atom, nitrogen atom and, carbon atom is 3.44, 3.04, and 2.55.

From this data we can conclude that oxygen is more electronegative than nitrogen. Also, the electronegativity difference of oxygen and carbon (0.89) is greater than the electronegativity difference of nitrogen and carbon (0.49).

Therefore, the electronegativity of the oxygen containing alcohol functional group (C-OH) will be greater than the electronegativity of the nitrogen (C-NH) containing amine functional group.
