Vedclass · Answer

(B) The condensation of phenols with phthalic anhydride in the presence of conc. $H_2SO_4$ is a test for the presence of a free $ortho$ or $para$ position relative to the $-OH$ group. $p$-Cresol has the $para$ position blocked by a $-CH_3$ group and the $ortho$ positions are also hindered or do not react to form the characteristic phthalein dye color under these specific conditions. Therefore,$p$-cresol does not give a coloured product.

Which one of the following phenols does not give colour when condensed with phthalic anhydride in the presence of conc. $H_2SO_4$?
