Question

When aromatic hydrocarbons are treated with chloroform and aluminum chloride, based on colours obtained, we cannot predict the type of aromatic system.

• A. True
• B. False

Answer 1

The correct option is B False

When aromatic hydrocarbons are treated with chloroform and aluminum chloride, based on colours obtained, we can predict the type of aromatic system. For example, if purple colour is observed, we can say that the system is phenanthrene. When green colour is obtained, we can say the system is anthracene. When blue colour is obtained, we can say that the system is naphthalene. When orange to red colour is obtained, we can say that the system is benzene.
