Questions & Step-by-Step Solutions

Which of the following compounds is an alkene?
Correct Answer: C4H8
  • Step 1: Understand what an alkene is. An alkene is a type of hydrocarbon that contains at least one carbon-carbon double bond.
  • Step 2: Look at the formula C4H8. This means there are 4 carbon atoms and 8 hydrogen atoms.
  • Step 3: Use the general formula for alkenes, which is CnH2n. For 4 carbon atoms (n=4), the formula would be C4H8.
  • Step 4: Since C4H8 matches the alkene formula, it indicates that there is a double bond between carbon atoms.
  • Step 5: Conclude that C4H8 is indeed an alkene because it has a carbon-carbon double bond.
