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, nonpolar, you've spotted those adequately. The thing to remember now is that molecules don't know they're polar or nonpolar, those are just names we come up with to describe our observations. In the case of ethanol, it has a polar bit and a non polar bit- the 'anol' vs the 'eth'. In this molecule, the carbon end is nonpolar enough to drag the polar end into the tolune, and vice versa, the polar end is polar enough as to drag the nonpolar end into water, which is why alcohol mixes with water.
