During four distinct reactions, W, X, Y and Z, 1 mol of an organic compound reacts with an excess amount of a reagent. Reaction table: - W: organic compound $(\text{CH}_2\text{COOH})_2$, reagent $\text{Na}$ - X: organic compound $\text{CH}_3\text{CH(OH)CH}_2\text{COOH}$, reagent $\text{Na}_2\text{CO}_3$ - Y: organic compound $\text{CH}_3\text{CH(OH)CH}_2\text{COOH}$, reagent $\text{NaOH}$ - Z: organic compound $\text{CH(OH)(COOH)CH}_2\text{COOH}$, reagent $\text{Na}$ Any gas formed is gathered and its volume is measured. All gas volumes are recorded at the same temperature and pressure. What is the sequence of the reactions from the largest total volume of gas collected to the smallest total volume of gas collected?
