Question

Hydrocarbons that contain only single bonds between the carbon atoms are called

• A. alkanes
• B. alkenes
• C. alkynes
• D. All of these

Answer 1

The Correct Option is A

Correct answer: alkanes 

Explanation:
Hydrocarbons are organic compounds made up of carbon and hydrogen. Based on the types of bonds between carbon atoms, they are classified as:

- Alkanes: Contain only single bonds between carbon atoms. They are also called saturated hydrocarbons. Example: methane (CH₄), ethane (C₂H₆)
- Alkenes: Contain at least one double bond between carbon atoms. Example: ethene (C₂H₄)
- Alkynes: Contain at least one triple bond between carbon atoms. Example: ethyne (C₂H₂)

Therefore, hydrocarbons with only single bonds are called alkanes.
