Explanation:
The Wurtz reaction between methyl chloride and sodium metal in presence of dry ehter can be written as: \({\text{2C}}{{\text{H}}_{\text{3}}}{\text{Cl + 2Na}}\xrightarrow{{{\text{Dry}}\,\,{\text{ether}}}}\mathop {{\text{C}}{{\text{H}}_{\text{3}}}{\text{ - C}}{{\text{H}}_{\text{3}}}}\limits_{{\text{Ethane}}} {\text{ + 2NaCl}}\) \(\Rightarrow 2\) moles of sodium metal reacts to give 1 mole of ethane. Also, 1 mole of Na metal \(=23 \mathrm{~g}\) \(\therefore 2\) moles of Na metal \(=23 \times 2=46 \mathrm{~g}\) Thus, \(46 \mathrm{~g}\) of sodium is required to prepare one mole of ethane from methyl chloride by Wurtz reaction.
