Unsaturated hydrocarbons are known as
Correct answer: B. Alkenes and alkynes
- A. Alkanes
- B. Alkenes and alkynes
- C. Alkynes
- D. Alkaloids
Explanation
Alkenes and alkynes are unsaturated hydrocarbons because they contain double and triple bonds, respectively, between carbon atoms. This results in a lower hydrogen-to-carbon ratio compared to alkanes. Option A is incorrect because alkanes are saturated hydrocarbons. Option C is incomplete as it only includes alkynes and not alkenes. Option D is unrelated as alkaloids are organic compounds not related to unsaturated hydrocarbons.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
