The correct order of boiling point is $:-$

$1.12 \, mL$ of a gas is produced at $STP$ by the action of $4.12 \, mg$ of alcohol with methyl magnesium iodide. The molecular mass of the alcohol is:

What is the order of acidic strength for the following compounds?

Select the correct statement.

$HOOC-COOH + HO^{18}CH_2-CH_2^{18}OH \xrightarrow[H^+]{\Delta} (A)$; Product $(A)$ is:

In the given reaction sequence,identify the correct reagents to prepare $A$ from $B$. The starting material is benzenesulfonic acid. The reaction with $\Delta / H_3O^+$ yields $B$ (benzene),and the reaction with $1. \text{Fused } NaOH, 2. H^+$ yields $A$ (phenol). Therefore,to prepare $A$ (phenol) from $B$ (benzene),the correct sequence of reagents is:
