VSEPR makes a distinction between electron group geometry, which expresses how electron groups (bonding and nonbonding electron pairs) are arranged, and molecular geometry, which …
Question: State whether the following molecules are polar or non-polar. Start by determining the Lewis structure, then the molecular geometry of the molecules.
Atoms assume a geometry dependent upon the electron pair geometry. Polarity. Bond dipoles point toward the more electronegative atom of the bond. Bond dipoles are "added" up to …
