Discuss the effect of E.W.G on the acidic strength of phenols. |
|
Answer» Solution :Electron withdrawing group [E.W.G] stablises the phenate ion by dispersing the negative charge on it. So E.W.G are more effective in inclosing the ACIDIC strength at the para POSITIOIN relative to ortho position. However, their EFFECT at the meta position is very LITTLE. So we have acidic strength of nitro phenol. p-nitro phenol > o-nitro phenol>m-nitrophenol>Phenol |
