Consider the following sequence of reactions

$C{F}_{3}I+KOH\left(aq\right)\to \left(X\right)+\stackrel{salt}{\left(Y\right)}$

 

 

 

 

 

(A) is also obtained by hydrolysis of Calcium Carbide  $\left(Ca{C}_2\right).$ 
If p = maximum number of atoms in a plane in a molecule of (X)
q = maximum number of identical bond angles involving three different atoms in one molecule of (Z).
And r = bond order between identical atoms in a molecule of (A), find the value of  $\frac{p+q+r}{2}.$
