Question

Compound MW gmol bp. C Solubility, b.w. g 100 mL density g mL 60.1 118 acetic acid miscible 1.049 isopentyl alcohol 881 130 Lisopemyl acetate 1302 112 0.25 0.S76 sulfuric acid miscible 1. What is the purpose of using sodium sulfate in the banana oil experiment? 2. Distillation is a method of purification that separates liquids based on boiling points. If compound A as a boiling point of 690C and compound B has a boiling point of50 C, which compound will be more concentrated in the vapor above the liquid if the liquid temperature is 48 C. Explain. 3. What could happen if you begin the distillation process with trace amounts of acid in your banana oil reaction mixture?

Explanation / Answer

2) Compund B is more volatile, that's why it's has a lower boiling point. Boiling point is when the vapor pressure of a liquid is equal to atmospheric pressure, that means, lower boiling point means more vapor above the liquid. Compound B will be more concentrated.

3) Banana Oil is an ester, esters can be hydrolized y a base or acid. IF heat is applied, hydrolisis will take plase and an alcohol and a carboxilic acid will be obtained (from banana oil)
