Question
Two organic compounds A and B have the same molecular formula $C_6H_{12}$. Write the names and structural formulae:
  1. If A is a cyclic compound.
  2. If B is an open chain compound.
  3. Which compound contains single bonds as well as a double bond?
  4. Which compound contains only single bonds?
✓

Answer

  1. If A is a cyclic compound, then $C_6H_{12}$ is the molecular formula of the compound named cyclohexane.
  1. If B is an open chain compound, then $C_6H_{12}$is the molecular formula of the compound named hexene.
  1. Hexene (B) is an unsaturated hydrocarbon comprising both single-bonded and double-bonded carbon atoms.
  2. Cyclohexane is an alkane which contains only single-bonded carbon atoms.
