Identify the correct statement with respect to unsaturated hydrocarbons.

Compounds of carbon having double bonds or triple bonds between their carbon atoms are called unsaturated compounds.

The correct answer is option 2. Compounds of carbon having double bonds or triple bonds between their carbon atoms are called unsaturated compounds.

The term "unsaturated hydrocarbons" refers to hydrocarbon compounds that contain carbon-carbon double bonds (C=C) or triple bonds (C≡C) in their molecular structures. Here's an explanation of the correct statement: Compounds of carbon having double bonds or triple bonds between their carbon atoms are called unsaturated compounds.

This statement is correct because in the context of hydrocarbons, which are compounds consisting of carbon and hydrogen only, unsaturated hydrocarbons specifically refer to those containing carbon-carbon double or triple bonds.

Double bonds (C=C):  If a hydrocarbon molecule has at least one carbon-carbon double bond, it is considered unsaturated. Examples include alkenes, which are hydrocarbons containing at least one C=C bond.

Triple bonds (C≡C): If a hydrocarbon molecule has at least one carbon-carbon triple bond, it is also considered unsaturated. Examples include alkynes, which are hydrocarbons containing at least one C≡C bond.

Contrastingly, saturated hydrocarbons, such as alkanes, have only single bonds (C-C) between carbon atoms.

So, the presence of double or triple bonds in the carbon-carbon framework characterizes unsaturated hydrocarbons.
