MCQ
Which acid is strongest or Which is most acidic
  • A
    $C{l_2}CH.COOH$
  • B
    $ClC{H_2}COOH$
  • C
    $C{H_3}COOH$
  • $C{l_3}C.COOH$

Answer

Correct option: D.
$C{l_3}C.COOH$
d
(d)Presence of $-I$ effect chlorine atom increases the acidic nature by withdrawing electrons

$\mathop {C{l_3}CCOOH}\limits_{trichloro{\mkern 1mu} \,\,acetic\,\,\,acid(Most{\mkern 1mu} \,\,acidic)}  > $ $\mathop {C{l_2}CHCOOH}\limits_{dichloro\,\,{\kern 1pt} acetic\,{\kern 1pt} acid}  > $ $Cl - C{H_2} - COOH > $ $C{H_3}COOH$
