A)
B)
C)
D) None of the above
Correct Answer: A
Solution :
Group or atom attached with \[-COOH\] group shows positive inductive effect increases electron density on oxygen atom, which suppress the ionisation of \[{{H}^{+}},\] hence, acidic strength decreases. Group or atom attached with \[-COOH\] group shows negative inductive effect decreases electron density on oxygen atom, which facilitate the ionisation of \[{{H}^{+}},\]hence acidic strength increases. Sequence of group shows negative inductive effect. \[-CHC{{l}_{2}}>-C{{H}_{2}}F>-C{{H}_{2}}Cl\]\[-C{{H}_{3}}\] group shows positive inductive effect and \[-H\] doesn't show any effect. So, \[>ClC{{H}_{2}}COOH>HCOOH>C{{H}_{3}}COOH\]You need to login to perform this action.
