Vedclass · Answer

(C) To determine the correct acidic strength order,we analyze the electronic effects of substituents on the acidity of the parent compounds:$A$. $p$-Nitrophenol is more acidic than phenol due to the $-M$ and $-I$ effects of the $-NO_2$ group,while $p$-methoxyphenol is less acidic due to the $+M$ effect of the $-OCH_3$ group. The correct order is $p$-Nitrophenol > Phenol > $p$-Methoxyphenol.$B$. $m$-Nitrobenzoic acid is more acidic than benzoic acid due to the $-I$ effect of the $-NO_2$ group. $m$-Hydroxybenzoic acid is also more acidic than benzoic acid due to the $-I$ effect of the $-OH$ group. The order given is incorrect.$C$. $o$-Toluic acid ($o$-methylbenzoic acid) is more acidic than $m$-toluic acid due to the ortho effect,which increases the acidity of ortho-substituted benzoic acids regardless of the nature of the substituent. $m$-Toluic acid is slightly more acidic than $m$-ethylbenzoic acid because the $+I$ effect of the ethyl group is stronger than that of the methyl group,making the conjugate base of $m$-ethylbenzoic acid less stable. Thus,$o$-Toluic acid > $m$-Toluic acid > $m$-Ethylbenzoic acid is the correct order.$D$. Benzoic acid is significantly more acidic than phenol,and phenol is more acidic than cyclohexanol. The order given is incorrect.
