A hydrocarbon in which all valencies are satisfied by single bonds is classified as a:
AAromatic hydrocarbon
BSaturated hydrocarbon
CUnsaturated hydrocarbon
DCyclic hydrocarbon
Answer & Solution
Correct answer: B. Saturated hydrocarbon
1. In ethane and propane, only single bonds join the atoms.
2. All valencies of carbon are satisfied by these single bonds.
3. Such compounds are called saturated hydrocarbons, also known as alkanes.
4. Rule out C: unsaturated hydrocarbons contain a double or triple bond.
