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

$20.44 g$

$6.00 g$

$4.00 g$

$10.22 g$

Molecular weight of $C_{6} H_{5} O H = 94$
Atomic weight of $B r = 80$
Amount of $B r$ utilized $= 480 g$
$∵ 94 g$ of $C_{6} H_{5} O H$ reacts with $480 g$ of bromine.
$∴ 2 g$ of $C_{6} H_{5} O H$ will react with $= \frac{480 \times 2}{94}$
$= 10.2 g$
