Ethyl chloride with nascent hydrogen produces_________________?
Correct answer: B. ethane
- A. methane
- B. ethane
- C. propane
- D. butane
Explanation
Nascent hydrogen reduces ethyl chloride by replacing the chlorine atom with hydrogen: C2H5Cl + 2[H] -> C2H6 + HCl, so ethane is formed. Students may choose methane by thinking the carbon chain is shortened, but reduction replaces the halogen without removing a carbon atom.

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.
