When one hydrogen atom of alkane is removed then it is called________________?
Correct answer: B. alkyl
- A. alkene
- B. alkyl
- C. aldehyde
- D. saturated hydrocarbon
Explanation
Removing one hydrogen atom from an alkane leaves an alkyl group, written as R-, which has one unpaired valence available for bonding. The likely mistake is choosing alkene, but an alkene is formed by removing two hydrogen atoms from neighbouring carbon atoms to create a double bond.

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.
