Definition of Permanent dipole and molecular polarity
Check what you remember
Read the wording for your board, then hide it and explain Permanent dipole and molecular polarity in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Exists only when the individual bond dipoles do not cancel by symmetry, so polarity is decided by combining electronegativity difference with shape, not by counting polar bonds alone.
