Which of the following is not considered as an error during the esterification reaction: (check all that applies) Add cold water directly to the reaction mixture after reflux ends Turn on the water circulation in the condenser All of the above Using sodium hydroxide to neutralize remaining acid The number of layers in a liquid-liquid extraction is equal: O O 3 o 2 It depends on the solvents used A mass of isoamyl alcohol (MW = 88 g/mol, d = 0.81 g/ml) reacts with excess acetic acid (MW = 60g/mol, d = 1.05 g/ml) and H2SO4 to yield under reflux 8 g of ester A (MW = 130 g/ mol, d = 0.876g/mL) and a by-product B. Determine the Volume needed of aclohol if the % yield of the ester is 75%. 8.9 O 10.6 O 7.2 6.8 X has a solubility of 10 g/20 mL in organic solvent and 8 g/10 mL in water. calculate Kd? 1.6 0 0.625 O 0.5 0.8
