Ethy1 chloride on reduction in the presence of Zn/HCI produces___________________?
Correct answer: C. Ethane
- A. n. butane
- B. Ethanol
- C. Ethane
- D. Diethy1 ether
Explanation
Reduction replaces the chlorine atom in ethyl chloride, CH3CH2Cl, with hydrogen: CH3CH2Cl + 2[H] -> CH3CH3 + HCl. The product is ethane, an alkane, so option c is correct. Ethanol is a common wrong choice because students remember substitution of ethyl chloride with hydroxide rather than reduction with Zn/HCl.

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.
