Hydrocarbon Quiz

What is the general formula for alkanes (Hydrocarbons with only single bonds)?

• CnH2n

• CnH2n+2

• CnHn+2

• CnH2n-2

Explain the concept of isomerism in hydrocarbons.

• Isomerism only occurs in inorganic compounds, not hydrocarbons.

• Isomerism refers to the phenomenon where two or more hydrocarbons have the same molecular formula but different structural or spatial arrangements.

• Isomerism refers to the phenomenon where hydrocarbons have different molecular formulas.

• Isomerism is not a concept applicable to hydrocarbons.

Differentiate between saturated and unsaturated hydrocarbon bonds.

• Saturated hydrocarbons have no bonds between carbon atoms, while unsaturated hydrocarbons have single or double bonds between carbon atoms.

• Saturated hydrocarbons have single bonds between carbon atoms, while unsaturated hydrocarbons have double or triple bonds between carbon atoms.

• Saturated hydrocarbons have double bonds between carbon atoms, while unsaturated hydrocarbons have single bonds between carbon atoms.

• Saturated hydrocarbons have triple bonds between carbon atoms, while unsaturated hydrocarbons have double bonds between carbon atoms.
