The unsaturated hydrocarbons which contain one or more double bonds are called-

Correct option is C

The correct answer is (c) Alkenes.
· Alkenes are unsaturated hydrocarbons that contain at least one carbon-carbon double bond in their molecular structure.
· They follow the general formula CₙH₂ₙ, where "n" represents the number of carbon atoms.
· The presence of a double bond makes alkenes unsaturated, meaning they have fewer hydrogen atoms than alkanes (which are saturated hydrocarbons).
· Common examples of alkenes include ethylene (C₂H₄) and propylene (C₃H₆).
Information Booster:
· Unsaturated Hydrocarbons: Compounds with one or more double or triple bonds, including alkenes (double bonds) and alkynes (triple bonds).
· Alkanes: Saturated hydrocarbons with single bonds only, following the formula CₙH₂ₙ₊₂.
· Alkynes: Unsaturated hydrocarbons containing one or more triple bonds, with the general formula CₙH₂ₙ₋₂.
· Importance of Alkenes: Alkenes are highly reactive due to their double bonds and are widely used in the petrochemical industry for making polymers and other chemicals.
