Question

Aniline (1 mole) react with bromine to give symmetrical tribromoanline. The amount of bromine required is:

• A. 3.0 moles
• B. 1.5 moles
• C. 4.5 moles
• D. 6.0 moles

Answer 1

The correct option is A 3.0 moles

Aniline is strongly activated compound.
The ortho and the para positions are strongly activated.
So, bromination of aniline gives tribromo product (2,4,6- tribromoaniline).
So, 3 moles of $B{r}_2$ are consumed
