Lewis dot method: If you build the molecule with single bonds you are left with each carbon atom having an unshared electron and only 7 electrons in the valence shell- form a doube bond and eah carbon achieves its octet
More sophisticated:-
hybridise each carbon sp2, overlap the the two sp2 hybrid orbitals on each carbon with an s orbital on the hydrogens to form C-H sigma bonds. Overlap the third sp2 hybrids to form a carbon-carbon single sigma bond.
Overlap the left over p orbital on each carbon to form a pi bond.
C2H2 is a carbon bond. This particular type of carbon bond is referred to as a triple bond, as it contains two pi bonds and a sigma bond.
one carbon atom in C2H2 forms four bonds one bond with hydrogen and a triple bond with other carbon.
The sp3 carbon hybrid bonds are found in cyclopentane. These are all single bonds on double or triple bonds are present.
The carbon "skeleton" has one double bond, the rest are single bonds

covalent, generally only metals non metal form ionic substances, therefore carbon and hydrogen are covalent. C2H2 is acetylene, ethyne and has a carbon carbon triple bond.

Peanut oil, a plant product, is an unsaturated fat, which means it contains at least one double bond.
A double bond is depicted like this : C=C. This would be a carbon-carbon double bond.
Ethylene has 4 single bonds (carbon to hydrogen) and 1 double bond (carbon to carbon).
triple bond, but it is also the shortest.
Carbon can form double bond, but chlorine will not form double bond.
