alleryThe presence of a double bond between two carbon atoms makes the compound
ASaturated with only single bonds
BAn alcohol
CA cyclic aromatic compound
DUnsaturated (alkene), general formula CₙH₂ₙ
Answer & Solution
Correct answer: D. Unsaturated (alkene), general formula CₙH₂ₙ
1. A C=C double bond means fewer hydrogens than the saturated alkane.
2. Unsaturated hydrocarbons with one C=C are called alkenes.
3. Alkene general formula: CₙH₂ₙ.
4. Alkynes with C≡C triple bond have CₙH₂ₙ₋₂.
