If ethanal, $\text{CH}_3\text{CHO}$, undergoes reaction with HCN and the resulting organic product is then hydrolysed using aqueous acid, organic compound Y is produced. If propanal, $\text{C}_2\text{H}_5\text{CHO}$, is heated under reflux with acidified potassium dichromate(VI), organic compound Z is produced. What is the difference between the relative molecular masses of compounds Y and Z?
