polar
NH is a polar covalent bond. The difference in electronegativity between nitrogen and hydrogen causes the electrons to be unequally shared, resulting in a partial negative charge on the nitrogen atom and a partial positive charge on the hydrogen atom.
Bases can be either polar or non-polar, depending on their chemical structure. Many common bases, such as sodium hydroxide (NaOH) and ammonia (NH₃), are polar due to their ability to form hydrogen bonds and their ionic or dipole-dipole interactions. However, some organic bases, like triethylamine, can be non-polar or less polar due to their hydrocarbon components. The polarity of a base influences its solubility in water and its reactivity in various chemical reactions.
A polar liquid is a liquid that does not have any/much of a hydrocarbon chain and has mainly OH, NH or even C=O or C=-N groups. As you increase the carbon chain, you become less polar. Polar solvents include water, dimethylformamide, ethanol, methanol, acetonitrile to name a few. Non polar solvents include pentane, hexane, toluene, heptane to name a few.
