Some Basic Concepts Of Chemistry

\(7.8 \mathrm{~g}\) of a compound having molecular formula \(\mathrm{C}_6 \mathrm{H}_6\), on reacting with \(\mathrm{CH}_3 \mathrm{COCl} / \mathrm{AlCl}_3\) gives \(8.4 \mathrm{~g}\) of a product which has molecular formula \(\mathrm{C}_8 \mathrm{H}_8 \mathrm{O}\). Calculate the percentage yield of the product \(\mathrm{C}_8 \mathrm{H}_8 \mathrm{O}\). (Given, atomic weights of \(\mathrm{H}, \mathrm{C}\) and \(\mathrm{O}\) respectively are 1, 12 and 16)
