is added to Grignard reagent

\left(\mathrm{CH}_3 \mathrm{Mgl}\right)

. If

1.56 \mathrm{~ml}

of a gas is produced at STP, the molar mass of alcohol will be nearly

View answer and explanation

Correct option: B

59 \mathrm{~g} \mathrm{~mol}^{-1}

Option C (

{B}_6 {H}_6

and alk.

{H}_2 {O}_2

) is correct because this represents hydroboration-oxidation, which converts alkenes to alcohols with anti-Markovnikov addition, resulting in 1-propanol from propene.

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:
