Why is the C – O bond length in phenols less than that in methanol ?
Arrange the following in order of increasing boiling point : Ethoxyethane, Butanal, Butanol, n-butane
How can phenol be prepared from anisole ? Give reaction.
Illustrate hydroboration – oxidation reaction with an example.
Which of the following, on reaction with CH₃MgI and subsequent hydrolysis, will form a primary alcohol ?
Alcohols have higher boiling points than other classes of compounds, namely hydrocarbons, ethers and haloalkanes of comparable molecular masses. Alcohols and phenols are acidic in nature. Electron withdrawing groups in phenol increase its acidic strength and electron releasing groups decrease it. Alcohols may be prepared by acid catalysed hydration of alkenes, hydroboration-oxidation reaction, from carbonyl compounds by catalytic reduction and the action of Grignard reagents.
