Give hydrolysis reaction of C_(2)H_(5)COO^(-) Na^(+) occur on the anode. |
|
Answer» Solution :`C_(2)H_(5)COO_((aq))^(-)` and `Na^(+)` ions are produced in aqueous solution of `C_(2)H_(5)COO^(-) Na^(+)`. REACTION occur on anode : (a) Anode is positive ELECTRODE, so oxidation of near by anion `C_(2)H_(5)COO^(-)` is occurred which loses electron and form ethyl FREE radical. (b) Butane is formed from the two ethyl free radical. `[C_(2)H_(5)COO^(-)] -= underset("Propanoate ions")(2CH_(3)CH_(3))-overset(O)overset(||)(C)-overset(..)underset(..)(O^(-)): RARR underset("Ethyl free radical")(2CH_(3)CH_(2)+2CO_(2) uarr) + 2e^(-)` (c) `underset("Ethyl free radicals")(2CH_(3)CH_(2) ) rarr underset("Butane")(CH_(3)CH_(2))-CH_(2)CH_(3)` [Total reaction on anode = a+b] `2CH_(3)CH_(2)COO^(-) rarr CH_(3)CH_(2)-CH_(2)CH_(3)+underset("(Oxidation)")(2CO_(2) + 2e^(-))` |
