Acids and alcohols can react with sodium metal to produce hydrogen gas. Acetic acid (CH₃COOH) is a weak acid that releases hydrogen when it reacts with sodium, while ethanol (CH₃CH₂OH) is an alcohol that also reacts in a similar manner. However, the compound CH₃CHCOOCH₃ does not release hydrogen when reacted with sodium, as it lacks the necessary acidic or alcoholic functional groups.
