What are the characteristics and properties of a 1,2-disubstituted alkene?

A 1,2-disubstituted alkene is a type of molecule with a carbon-carbon double bond where each carbon atom is attached to two other groups. This type of alkene is typically more stable than other types due to the presence of substituents on both carbons of the double bond. The properties of a 1,2-disubstituted alkene can include increased reactivity in certain chemical reactions and the potential for geometric isomerism.
