i) Name the product obtained when phenol is treated with chloroform in the presence of NaOH. ii) Name the above reaction. iii) What is the product obtained when phenol is treated with con. HNO 3? iv) Write the structure and IUPAC name of the above product. v) Ethanol and propane have comparable molecular masses but their boiling points differ.

Answer: Treating phenol with chloroform in the presence of aqueous NaOH results in the formation of a tri-substituted phenol, also known as a trichlorophenol. The reaction is a type of halogenation reaction, where the hydrogen atoms on the phenol molecule are replaced with chlorine atoms from the chloroform molecule.
