Give the equations of reactions for the preparation of phenol from cumene.
To prepare phenol,cumene is first oxidized in the presence of air of cumene hydro-peroxide.
Then,cumene hydroxide is treated with dilute acid to prepare phenol and acetone as by-products.

Arrange the following compounds in increasing order of their boiling points:

The reaction 
suggests that phenol is :
In the reaction R–OH + HCl $\xrightarrow{\text{ZnCl}_2}$ RCl + H$_2$O, what is the correct order of reactivity of alcohols?
