Solution

The correct option is B 1 : 1
The reactions are :
$3 C_{2} H_{5} O H + P C l_{3} \to 3 C_{2} H_{5} C l + H_{3} P O_{3}$

$C_{2} H_{5} O H + P C l_{5} \to C_{2} H_{5} C l + P O C l_{3} + H C l$

The mole ratio of $P C l_{3}$ and $P C l_{5}$ in the mixture is $1 : 1$ .

Option B is correct.
