The product $(B)$ of the reaction is:

Identify the major product of the reaction when the given compound is hydrolyzed and heated strongly.

Which of the following is the correct decreasing order of boiling points for the given organic compounds?

The reaction of $CH_3CO_2C_2H_5$ with sodium ethoxide and ethanol gives product $X$. Heating $X$ in the presence of an acid gives $Y$. What is $Y$?

Arrange the acidity of the given four compounds in decreasing order:
$(I)$ $CH_3COCH_2COCH_3$
$(II)$ $CH_3COCH_3$
$(III)$ $CH \equiv CH$
$(IV)$ $CH_3CHO$
Select the correct answer from the codes given below:

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 $(b)$.
$(a)$ $3\text{-hydroxy-5-formylbenzoyl chloride} + x \ PhMgBr \xrightarrow{\text{excess}} (A)$
$(b)$ $2,5\text{-dioxocyclohexanecarboxylic acid} \xrightarrow{\Delta} (B) + (C) \uparrow$
