Why it matters

This objective helps connect Structure, bonding and reactivity to exam-style questions, flashcards, and revision notes for Alkenes.

Quick student answer

Which of the following statements correctly describes alkenes?

Direct answer

B) Alkenes contain at least one carbon-carbon double bond.

Key terms

  • Unsaturated Hydrocarbon: A hydrocarbon that contains at least one carbon-carbon double or triple bond, allowing for additional reactions.
  • Addition Reaction: A chemical reaction in which atoms are added to a molecule, typically occurring with alkenes due to their double bonds.

Common trap

Confusing alkenes with alkanes: Remember that alkenes are unsaturated due to the presence of double bonds, while alkanes are saturated with only single bonds.
