The molecular formula of diphenyl methane, \( \text{C}_{13}\text{H}_{12} \), is \( \text{C}_{13}\text{H}_{12} \). How many structural isomers are possible when one of the hydrogens is replaced by a chlorine atom?
Show Hint
When substituting atoms in aromatic compounds, the possible isomers depend on the symmetry and positions of the substituent groups on the aromatic rings.
Step 1: Replacing one hydrogen atom in diphenyl methane with chlorine will produce structural isomers depending on the position of chlorine in the benzene ring. Step 2: Considering the positions of the substituents on the phenyl rings, there are a total of 7 possible isomers.
