Question

What amount of bromine will be required to convert $2g$ of phenol into $2,4,6$-tribromophenol?

• A. $4.0$
• B. $6.0$
• C. $10.2$
• D. $20.4$

Answer 1

The correct option is C $10.2$

$C_6{H}_{6}OH+3B{r}_2⟶$ the given figure.

So, $94g$ $3\times 160g$

$94g$ of phenol reacts with $3\times 160=480g$ of bromine.

$\therefore 2g$ of phenol reacts with $=\frac{3\times 160\times 2}{94}=10.2g$ of Bromine.
