Which of the following statements regarding phenols is not correct?

View answer and explanation

Correct option: C

Phenols are soluble in both aqueous

\mathrm{NaOH}

and aqueous

\mathrm{NaHC}{\mathrm{O}_3}

Option C (Phenols are soluble in both aqueous

\mathrm{NaOH}

and aqueous

\mathrm{NaHC}{\mathrm{O}_3}

) is not correct because phenols are soluble in aqueous NaOH due to the formation of sodium phenoxide, but they are not soluble in aqueous NaHCO3 because they are weaker acids than carbonic acid.

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:
