When two moles of ethyl chloride react with two moles of sodium in the presence of ether what will be formed ?
Correct answer: D. 1 mole of butane
- A. 2 moles of ethane
- B. 1 mole of ethane
- C. 2 moles of butane
- D. 1 mole of butane
Explanation
The Wurtz reaction couples two ethyl groups: 2 C2H5Cl + 2 Na → C2H5-C2H5 + 2 NaCl. One molecule of butane is therefore produced from two moles of ethyl chloride, so the product amount is 1 mole of butane. Students may choose 2 moles of butane by assuming each mole of ethyl chloride independently gives a molecule of product.

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.
