What is the molar mass of product hydrocarbon when 2 moles of methyl bromide reacts with large excess of sodium in dry ether?
  1. $15.0 \mathrm{~g} \mathrm{~mol}^{-1}$
  2. $30.0 \mathrm{~g} \mathrm{~mol}^{-1}$
  3. $7.5 \mathrm{~g} \mathrm{~mol}^{-1}$
  4. $40.0 \mathrm{~g} \mathrm{~mol}^{-1}$

Solution


Thus, the molar mass of the product formed, i.e., ethane is $30.0 \mathrm{~g} \mathrm{~mol}^{-1}$.
