Question

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?

• A. 6
• B. 8
• C. 4
• D. 7

Hint:

When substituting atoms in aromatic compounds, the possible isomers depend on the symmetry and positions of the substituent groups on the aromatic rings.

Answer 1

The Correct Option is D

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.

Final Answer: \[ \boxed{7} \]
