The bond is then said to be polar. The term polar molecule can mean two things: (1) simply that there are polar bonds present in the molecule, (2) that the molecular structural arrangement of bonds and electron lone pairs gives rise to a permanent molecualr dipole moment.eport Abuse. A polar molecule has a difference in electronegativity between atoms across the entire molecule. The differently charged atoms are called dipoles. A commonly used example is water, H2O. The oxygen molecule has a high electronegativity compared to the hydrogen molecules, so it exhibits a negative dipole.
Polar molecules have atoms that are able to form hydrogen bonds, typically hydroxyl (-OH) or carbonyl (C=O) groups. The DNA backbone consists of alternating ribose (sugar) and phosphate molecules. Phosphate is negatively charged, which is why DNA macromolecules are predominately negative.
