| The alkene carbon-carbon double bond is made from two sp trigonally hybridized carbons. |
| The naming of geometrical isomers reflects the position of the atoms or groups on each of the carbon atoms in the double bond. |
| Since there are two atoms bound to the sulfur atom, there must be one double bond. |
| Where they are on opposite sides of the double bond, the arrangement is the trans arrangement. |
| A double bond happens when two electrons are shared or exchanged in a bond. |
| On the other hand, in polar conjugated systems such as protonated Schiff bases the funnel shows a structure with just one twisted double bond. |
