The same rule is applied for any other double or triple bond. So, when you see a double bond count it as two single bonds when you see a triple bond cut it as three single bonds.

WebJul 19, 2024 · The wedge and dash model is based on valence shell electron pair repulsion (VSEPR). One of the central tenets of VSEPR theory is that when bonding occurs between atoms with lone pairs of electrons, they will be arranged so that these lone pairs lie along one axis. For example, they will be pushed apart by their mutual electrostatic attraction.
