VSEPR: Linear Electronic Symmetry

Molecules with Linear Electronic Symmetry

	Electronic Structure:	AB₂
	Electronic Geometry:	linear
	Hybridization at central atom:	sp

With only two substituents on the central atom, molecules with the general AB₂ electronic structure have just one geometry. Both the electronic and the molecular geometry are linear. This includes molecules with ABE structure (not shown), such as the cyanide ion (CN^-).
