Question

If an aqueous solution of X on heating with $N a O H + C a O$ followed by acidfication produced methane gas and $C O_{2}$ gas.
$X N a O H (a q .) - ------ \to Y N a N H_{2} - ---- \to Δ Z C l_{2} / h v - --- \to P$

$P N a, d r y e t h e r - ------- \to Q C l_{2} / h v - --- \to R a l c . K O H - ----- \to S$

$S B r_{2} - -- \to C C l_{4} T i i) N a N H_{2} - ------ \to i) a l c . K O H U F e t u b e - --- \to R e d h o t W$

From the given sequence of reactions, $W$ is the final product in which x is the number of sigma bonds and y is the number of $π$ bond(s) then $x + y =$ .
