Calculate the value of $x + \text{molecular mass of } (C)$,where $x$ is the number of moles of $PhMgBr$ consumed in reaction $(a)$ and $(C)$ is the gas evolved in reaction $(b)$.
$(a)$ $3\text{-hydroxy-5-formylbenzoyl chloride} + x \ PhMgBr \xrightarrow{\text{excess}} (A)$
$(b)$ $2,5\text{-dioxocyclohexanecarboxylic acid} \xrightarrow{\Delta} (B) + (C) \uparrow$

In the reaction $CH_3COOH$ $\xrightarrow{LiAlH_4} (A)$ $\xrightarrow{I_2 + NaOH} (B)$ $\xrightarrow{Ag \text{ (Dust)}} (C)$,the final product $(C)$ is

Match List-$I$ with List-$II$:

List-$I$ (Test)	List-$II$ (Identification)
$A$. Bayer's test	$I$. Phenol
$B$. Ceric ammonium nitrate test	$II$. Aldehyde
$C$. Phthalein dye test	$III$. Alcoholic-$OH$ group
$D$. Schiff's test	$IV$. Unsaturation

Choose the correct answer from the options given below:

What are the products formed at the anode during Kolbe synthesis?

Choose the correct option$(s)$ for the following reaction sequence. Consider $Q$,$R$ and $S$ as major products.

In the following reaction sequence,the major product $P$ is formed. Glycerol reacts completely with excess $P$ in the presence of an acid catalyst to form $Q$. Reaction of $Q$ with excess $NaOH$ followed by the treatment with $CaCl_2$ yields $Ca$-soap $R$,quantitatively. Starting with one mole of $Q$,the amount of $R$ produced in gram is. . . .
