Vedclass · Answer

(NONE) Let us analyze each option:$A$: The order of acidic strength for methylbenzoic acids is $o- > m- > p-$. This is correct due to the ortho effect and electronic effects.$B$: The stability of the carbocation with a positive charge adjacent to an oxygen atom is significantly higher due to resonance stabilization by the lone pair on oxygen. The given order is correct.$C$: The $-I$ effect of the chlorine atom increases the acidity of chloroacetic acid compared to formic acid. The order $ClCH_2-COOH > H-COOH$ is correct.$D$: The correct order of acidic strength for nitrophenols is $p-Nitrophenol > o-Nitrophenol > m-Nitrophenol$. This is correct due to the strong $-I$ and $-M$ effects of the nitro group at ortho and para positions,with para being stronger due to less steric hindrance and effective resonance.
