Correct order of boiling point for given compounds is:-

View answer and explanation

Correct option: D

{C_2}{H_5}OH > C{H_3}OC{H_3} > {C_2}{H_6}

Option D (

{C_2}{H_5}OH > C{H_3}OC{H_3} > {C_2}{H_6}

) is correct because alcohols have hydrogen bonding, ethers have dipole-dipole interactions, and alkanes have only London dispersion forces, with the strength of intermolecular forces determining the boiling point.

Ethers are made free from peroxide linkage on distilling impure sample with: The product 'B' in the following reaction is

{\text{C}}{{\text{H}}_3}{\text{C}}{{\text{H}}_2}{\text{OH}}\xrightarrow{{{\text{PCC}}}}{\text{A}}\xrightarrow[{\left( {{\text{ii}}} \right){\text{ }}{{\text{H}}_2}{\text{O/}}{{\text{H}}^ + }}]{{\left( {\text{i}} \right){\text{ HCN}}}}{\text{B}}

Fenton’s reagent is: Assertion:- Isopropyl benzene reacts with

\mathrm{O}_2

and acid gives phenol.

Reason:- Initially isopropyl benzene converts into 2-phenyl propan-2-ol. When an ether is treated with

{\mathrm{P}_2}{\mathrm{S}_5}

we get: Physical properties of:
