$[Y]$ will be :

$I.$ There is no $P_{\pi } -P_{\pi }$ bonds present in the molecule

$II.$ There are eight lone pair of electrons

$III.$ Each $S$ atom is $sp^3$ hybridised

$\gamma_{1} A +\gamma_{2} B \rightarrow \gamma_{3} C +\gamma_{4} D$

Concentration of $C$ changes from $10\, mmol$ appearance of $D$ is $1.5$ times the rate of disappearance of $B$ which is twice the rate of disappearance $A$. The rate of appearance of $D$ has been experimentally determined to be $9 \,m\,mol$ $dm ^{-3} s ^{-1}$. Therefore the rate of reaction is $......\,m\,mol\, dm ^{-3} \,s ^{-1}$. (Nearest Integer)

The correct statement ($s$) about $P, Q, R$, and $S$ is (are)

($A$) $P$ and $Q$ are monomers of polymers dacron and glyptal, respectively.

($B$) $P, Q$, and $R$ are dicarboxylic acids.

($C$) Compounds $Q$ and $R$ are the same.

($D$) $R$ does not undergo aldol condensation and $S$ does not undergo Cannizzaro reaction.
