In addition to water, which of the following could be found during the incomplete combustion of a hydrocarbon?
Correct answer: A. Carbon, carbon monoxide and hydrogen
- A. Carbon, carbon monoxide and hydrogen
- B. Carbon and oxygen
- C. Carbon monoxide and hydrogen
- D. Carbon and carbon monoxide
Explanation
a) Carbon, carbon monoxide, and hydrogen:During the incomplete combustion of a hydrocarbon, if there is not enough oxygen available, the hydrocarbon may not completely burn. This can result in the formation of carbon, carbon monoxide, and hydrogen as byproducts. The carbon is formed due to the incomplete combustion, while carbon monoxide and hydrogen are formed through various chemical reactions in the process.

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.
