Step-by-Step Explanation Step 1: Recognize the Type of Reaction The question describes a reaction in which carbon dioxide is removed from the substrate. The removal of CO₂ from a compound is referred to as a decarboxylation reaction. Step 2: Identify the Key Reagent for Decarboxylation Decarboxylation of carboxylic acids (or their salts) is typically carried out by heating them with soda lime. Soda lime is a mixture of $ \text{NaOH} $ and $ \text{CaO} $. In this reaction, $ \text{CaO} $ (in combination with $ \text{NaOH} $) plays a critical role in ensuring that the carboxylate decomposes to form the corresponding hydrocarbon (or substituted hydrocarbon) and releases carbon dioxide, $ \text{CO}_2 $. Step 3: Conclusion Since the question specifically asks for the missing reagent required to bring about this decarboxylation, the answer is $ \text{CaO} $. In practice, $ \text{CaO} $ is used together with $ \text{NaOH} $ as soda lime.
