Multiple choice The increasing order of basic strength of Cl-, CO32-, CH3COO-, OH- and F- will be Cl- < F- < CH3COO- < CO32- < OH- Cl- < F- < CO32- < CH3COO- < OH- CH3COO- < Cl- <f>- < CO32- < OH-</f> None of these Reveal answer Fill a bubble to check yourself A Correct answer Explanation This option is correct because we know that lower will be the acidic strength higher will the basic strength of the conjugate base, since conjugate acids of the following bases follow the order of strength as HCl > HF > CH3COOH > H2CO3 > H2O.
