These hydrocarbons contain one or more double or triple bonds between the two adjacent carbon atoms in their structure:
Correct answer: D. Alkenes and alkynes
- A. Alkenes and alcohol
- B. Alkenes and cycloalkanes
- C. Alkanes and alkyl halides
- D. Alkenes and alkynes
- E. Alkanes and alkenes
Explanation
Alkenes are unsaturated hydrocarbons characterized by at least one carbon-carbon double bond (C=C) and have the general formula CₙH₂ₙ. They are more reactive than alkanes due to the presence of the double bond, allowing for various chemical reactions such as addition reactions. In contrast, alkynes are also unsaturated hydrocarbons but contain at least one carbon-carbon triple bond (C≡C), with the general formula CₙH₂ₙ₋₂. Alkynes are even more reactive than alkenes, making them useful in a variety of chemical synthesis processes. Both alkenes and alkynes are essential in organic chemistry, serving as key intermediates and building blocks for more complex organic compounds.

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.
