The correct order of boiling points of the compounds given below is-
$A$) Methoxy ethane
$B$) Propan-$1$-ol
$C$) Propanal
$D$) Propanone

From the following,identify the reactions that give alcohol as the product.
$(i)$ $Cyclohexylidenemethane \xrightarrow[(ii) H_2O_2/NaOH]{(i) B_2H_6}$
(ii) $Methyl \ benzoate \xrightarrow{H_2/Catalyst}$
(iii) $Acetophenone \xrightarrow{NaBH_4/MeOH}$
(iv) $2,2-Dichloropropane \xrightarrow{H_2O/NaOH}$

List-$I$ contains reactions and List-$II$ contains major products. Match each reaction in List-$I$ with one or more products in List-$II$ and choose the correct option.

Identify $A$ in the following chemical reaction:

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:
