Which one of the following reactions shows the combustion of a saturated hydrocarbon?
Correct answer: B. CH4 + 2O2 → CO2 + 2H2O
- A. C2H4 + 3O2 → 2CO2 + 2H2O
- B. CH4 + 2O2 → CO2 + 2H2O
- C. CH4 + 12 O2 = CH3OH (conditions: (Conditions:Cu, 400°C, 200 atm)
- D. C2H2 + 5/2 O2 → 2CO2 + H2O
Explanation
Key points here: The products of combustion are always H2O and C02 2-saturated means those having in which carbon form only single bonds

About Alkanes
Alkanes are saturated hydrocarbons containing only carbon-carbon and carbon-hydrogen single bonds, with the general formula CnH2n+2 for open chains. Their structure, isomerism, IUPAC nomenclature, physical properties, combustion, free-radical halogenation and conformations are covered, including the difference between substitution in alkanes and addition in unsaturated hydrocarbons.
