Answer» Solution :When ETHYL cyanide is boiled with AQUEOUS sodium HYDROXIDE, sodium PROPIONATE is obtained, which on treating with dilute hydrochloric ACID, gives propionic acid. `CH_(3)-underset("ethyl cyanide")(CH_(2)-C)-=N+NaOH+H_(2)Ooverset(Delta)(to)CH_(3)-underset("sodium propionate")overset(O)overset(||)(C)-ONa+NH_(3)` `CH_(3)-CH_(2)-overset(O)overset(||)(C)-ONa+HCl to underset("propionic acid")(CH_(3)-CH_(2))-overset(O)overset(||)(C)-OH+NaCl` |
