Compounds of carbon containing carbon-carbon double bond are known as:

Correct option is C

The correct answer is (c) unsaturated compounds.

Explanation:

Compounds of carbon that contain carbon-carbon double bonds are called unsaturated compounds. The term unsaturated refers to the presence of one or more double bonds between carbon atoms in the molecule, which means the compound has fewer hydrogen atoms attached to the carbon chain compared to saturated compounds.

• Carbon-carbon double bonds are characteristic of unsaturated hydrocarbons, such as alkenes. For example, ethene (C₂H₄) is an alkene where two carbon atoms are bonded by a double bond.

• Saturated compounds, on the other hand, are hydrocarbons that only contain single bonds between carbon atoms. These are called alkanes, like methane (CH₄) and ethane (C₂H₆).

Information Booster:

• Alkenes (unsaturated compounds): Alkenes are a type of unsaturated compound that specifically contain one or more carbon-carbon double bonds. The simplest example is ethene (C₂H₄). These compounds are reactive because the double bond is relatively easy to break and participate in various chemical reactions, such as addition reactions.

• Alkynes: These are also unsaturated hydrocarbons, but they contain carbon-carbon triple bonds. For example, ethyne (C₂H₂), commonly known as acetylene, is an alkyne. Alkynes are more reactive than alkenes due to the triple bond.

• Saturated compounds (alkanes): Alkanes are hydrocarbons that only have single bonds between carbon atoms, making them "saturated" with hydrogen atoms. An example of an alkane is methane (CH₄), the simplest hydrocarbon.

• Unsaturation in Chemistry: The presence of double or triple bonds in a molecule makes it unsaturated, which often leads to different physical and chemical properties compared to saturated compounds. For example, unsaturated fats, which contain double bonds, tend to be liquid at room temperature (like olive oil), while saturated fats are typically solid (like butter).
