What is called a battery? Explain its characteristics and describe dry cell and mercury cell.
An aromatic compound ‘A’ on treatment with $CHCl_3 / KOH$ gives two compounds ‘B’ and ‘C’. Both B and C give the same product ‘D’ when distilled with zinc dust. Oxidation of D gives E having molecular formula $C_7H_6O_2$. The sodium salt of E on heating with sodalime gives F which may also be obtained by distilling A with zinc dust. Identify A to F.
