The N-H bond is polar due to the difference in electronegativity between nitrogen (N) and hydrogen (H). Nitrogen is more electronegative than hydrogen, resulting in a partial negative charge on the nitrogen atom and a partial positive charge on the hydrogen atom. This polarity contributes to the overall polarity of molecules containing N-H bonds, such as amines and ammonia.
The OH bond is more polar than the NH bond because oxygen is more electronegative than nitrogen, leading to a greater difference in electronegativity between oxygen and hydrogen. This means the OH bond has a greater separation of charge and greater polarity than the NH bond.
To determine a polymer's polarity, you can assess its chemical structure, focusing on the presence of polar functional groups like -OH, -NH, or -COOH. Additionally, techniques such as solubility tests in various solvents can provide insights, as polar polymers typically dissolve in polar solvents. Spectroscopic methods, like infrared (IR) spectroscopy, can also help identify polar bonds and functional groups, indicating the polymer's polarity. Lastly, measuring the dielectric constant can give a quantitative measure of polarity.

No. NH is not a chemical compound. NH3, ammonia, is a base.
