$(I)$ Acid chloride                   $(II)$ Aldehyde

$(III)$ Ketone                          $(IV)$ Ester

Select the correct answer from the codes given below :

$X_2 + Y_2 \rightarrow 2XY,$ is given below :

$(i)\,\, X_2 \rightarrow X + X\, (fast)$

$(ii)\,\,X + Y_2 \rightleftharpoons XY + Y\, (slow)$

$(iii)\,\,X + Y \rightarrow XY\, (fast)$

The overall order of the reaction will be

Isomer $(P) \Rightarrow$ Can be prepared by Gabriel phthalimide synthesis

Isomer $(Q) \Rightarrow$ Reacts with Hinsberg's reagent to give solid insoluble in $NaOH$

Isomer (R) $\Rightarrow$ Reacts with $HONO$ followed by $\beta$-naphthol in $NaOH$ to give red dye.

Isomers $( P ),( Q )$ and $( R )$ respectively are
