Why is the $\displaystyle \mathrm{C}-\mathrm{O}$ 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.

Give mechanism of the following reaction : $\displaystyle \mathbf{2}+\mathbf{1}=\mathbf{3}$ $\displaystyle \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OH} \xrightarrow[413 \mathrm{~K}]{\mathrm{H}_{2} \mathrm{SO}_{4}} \mathrm{CH}_{3} \mathrm{CH}_{2}-\mathrm{O}-\mathrm{CH}_{2} \mathrm{CH}_{3}+\mathrm{H}_{2} \mathrm{O}$

Illustrate hydroboration - oxidation reaction with an example.
