Answer:
Ethyne
Explanation:
Hydrocarbons are compounds containing carbon (C) and hydrogen (H) atoms. Here, the carbon-carbon bonds form the skeletal structure in which the C atoms can be linked to form linear chains or cyclic structures.
The C-C bonds are essentially covalent. The bonds can be single or multiple bonds. Structures in which the C atoms are linked by single bonds are called saturated hydrocarbons where multiple bonds between C atoms results in unsaturated hydrocarbons.
In the given examples, ethyne (C₂H₂) is an unsaturated hydrocarbon. Here, each C atom is attached to one H atom via a single bond and to another C atom via a triple bond.
