Which of the following iscorrect ? (a) the conjugate acid of `HO(CH_(2))_(3)NH_(2)` is `H_(2)overset(+)O(CH_(2))_(3)NH_(2)` is (b) The conjugate base of `HO(CH_(2))_(3)NH_(2)` is `barO (CH_(2))_(3)overset(+)underset(+)(N)H_(2)` (C ) The conjugate acid of `HO(CH_(2))_(3)NH_(2)` is `HO(CH_(2))_(3)NH_(2)` (d) The conjugate base of `HO(CH_(2))_(3)NH` .A. (b),(C )B. (a),(b)C. (c ),(d)D. (a),(d)

Answer» Correct Answer - A
Conjugate acid `hArr H^(+)` + conjugate base The conjugate acid of `HO(CH_(2))_(3)NH_(2)` is `HO(CH_(2))_(3) overset(+)NH_(3)` because `NH_(2)` is a more basic site than `oH` The conjugate base of `HO(CH_(2))` is `barO(CH_(2))_(3) NH_(2)` because `H-O` is more acidic than `H-N` .
