Definitions for "Polarised"
To be polarised means to have two opposing attributes. When referring to cells it usually means that the electrical charge is different between the intracellular and extracellular space. Close this window
A bond is polarised if the electron density is not uniformly distributed along it, so that a dipole is created - this tends to happen when electronegative or electropositive (relative to carbon) elements are bonded to carbon. The bond will then have a partially positively charged end 'δ+', and a partially negatively charged end 'δ-'.
