Vedclass · Answer

(B) The boiling point of these ortho-substituted phenols depends on the extent of intramolecular hydrogen bonding and molecular weight.In $o$-fluorophenol $(I)$,$o$-chlorophenol $(II)$,and $o$-bromophenol $(III)$,intramolecular hydrogen bonding is present in all three.However,the boiling point is primarily influenced by the molecular weight and the strength of intermolecular forces (van der Waals forces) which increase with the size of the halogen atom.As the size of the halogen atom increases from $F Therefore,the correct order of boiling point is $III > II > I$.

The correct order of boiling point for the given compounds is:
