Your first step should be to analyse the compound. For example, if the compound is carbon, you know it always has a valence of four, so, if it has a formula C2H4 (ethylene) it obviously has a double bond. There are difficulties here because benzene C6H6 can be considered to have 6 1.5 C-C bonds, being aromatic.
For example, of the isomers of butene, the two methyl groups of (Z)-but-2 -ene (a.k.a. cis -2-butene) face the same side of the double bond, and in (E)-but-2-ene (a.k.a. trans -2-butene) the methyl groups face the opposite side.ike a single covalent bond, double bonds can be described in terms of overlapping atomic orbitals, except that, unlike a single bond (which consists of a single sigma bond), a carbonâcarbon double bond consists of one sigma bond and one pi bond.
