On prolonged nitration of phenol with conc. $HN{O_3}$ and

WebThe reaction of phenol with nitrous acid (10 –4 M < [N III] < 10 –2 M) and nitric acid (10 –3 M < [N V] < 0.3M) in aqueous sulphuric acid (19–45% H 2 SO 4) at 25 °C gives rise to p … WebThis can be done by first reating the phenol with $\ce{HNO2}$ Which gives us this . Then reacting with dil $\ce{HNO3}$ we get 90% yield of para nitro phenol . This happens because $\ce{N=O}$ has a very strong $- I$ effect thus it concentrates the electrons more towards the para position so on reacting with dil $\ce{HNO3}$ we get max yield of para historic mesilla templates banners
