In K a , Acidic strength depends upon -I effect of - COOH group In K a Acidic strength depends upon + I effect of - COO group after removal of H +

Q. Order of $K_{a_{1}} & K_{a_{2}}$ in the following carboxylic acids:

$K_{a_{1}} = I > II > III > I V$ $K_{a_{2}} = I > II > III > I V$

$K_{a_{1}} = I V > III > II > I$ $K_{a_{2}} = I > II > III > I V$

$K_{a_{1}} = II > III > I V > I$ $K_{a_{2}}^{a} = I > I V > III > II$

$K_{a_{1}} = II > I V > I >$ III $K_{a_{2}}^{T} = I > III > I V > II$

In $K_{a}$ , Acidic strength depends upon $- I$ effect of $- COO H$ group In $K_{a}$ Acidic strength depends upon $+ I$ effect of $- COO$ group after removal of $H^{+}$

Q. Order of Ka1​​&Ka2​​ in the following carboxylic acids:

Ka1​​=I>II>III>IV Ka2​​=I>II>III>IV

Ka1​​=IV>III>II>I Ka2​​=I>II>III>IV

Ka1​​=II>III>IV>I Ka2​a​=I>IV>III>II

Ka1​​=II>IV>I> III Ka2​T​=I>III>IV>II
