Question

Which is the limiting reagent in the procedures for synthesizing 2-methylpropyl acetate given below? H2SO4 0 YOH + Hoi Ho You H₂O 2-Methylpropanol Acetic acid 2-Methylpropyl acetate "In a 250-ml round-bottom flask, acetic acid (57 mL, 1.0 mol), 3-methylpropanol (37 g, 0.50 mol), and H2S04 (10 mL) were refluxed for 1 h.” Acetic acid (1.0 mol) 2-Methyl propanol (0.5 mol) H2S04 (0.18 mol) 2-Methylpropyl acetate (0.3 mol) QUESTION 2 Consider scaling down the procedure below for synthesizing 2-methylpropyl acetate. How many moles of acetic acid will be needed if the scaled down procedure uses 0.1 moles of 2-methylpropanol? Тон . . . . , но 2-Methylpropanol Acetic acid 2-Methylpropyl acetate "In a 250-ml round-bottom flask, acetic acid (57 mL, 1.0 mol), 3-methylpropanol (37 g, 0.50 mol), and H2S04 (10 mL) were refluxed for 1 h." 2.0 mol O 0.5 mol 0.2 mol 0.018 mol

Answer 1

Limiting reagent in the reaction is the reagent which is present in less amount as compared to other reagents also considering its stoichiometry - In the given reaction Imole of acetic and will react with Imole of 2-methylpropanol but it is in less amount so 2-methy propanol is limiting reagent. H₂ So here acts ascatalyst. In scaling down reactions conditions are same only the amount of reagents reacting is decreased. In new reaction condition 2-methylpropanol is scaled down 5 times so acetic csdsige drie be scaled down stimes so 1.0 - 0.2 males
