View Solution Describe the mechanism by which the hydroxyl group attached to an aromatic ring is more acidic than the hydroxyl group attached to the alkyl group. How does the presence of a nitro group in phenol affect its acidic nature ?
Phenol isa very weak acidand the position of equilibrium lies well to the left. Phenol can lose a hydrogen ion because the phenoxide ion formed is stabilised to some extent. The negative charge on the oxygen atom is delocalised around the ring. ... That is why phenol is only a very weak...

(Supplementary Fig.3) confirmed the preservation of its structural features due to the covalent nature of taurine immobilization on graphene. To further check the stability and heterogeneity of the catalyst, we performed a leaching test, whereby the catalyst was separated from the reaction mixture ...
Trinitrotoluene (TNT), a pale yellow,solid organic nitrogen compoundused chiefly as an explosive, prepared by stepwise nitration of toluene. Why picric acid is called an acid? We know phenol shows acidic nature. 2,4,6-Trinitrophenol is highly acidic in nature as three electron withdrawing groups...
At oil processing temperatures, naphthenic acids show corrosion activity and although there has been numerous works to determine the specific factors, the nature of naphthenic acid corrosion and the factors controlling it are still not completely understood (Kane and Cayard, 1999, 2002Kane and Cayard...
