A student weighs out 1.394 g of t-butyl alcohol into a large test tube and measures the freezing point of the pure solvent to be 21.50 °C. Next the student weighs out 1.068 g of water and adds it to the test tube with the t-butyl alcohol and measures the freezing point of the mixture to be 15.0 °C. What is the freezing point depression constant, Kf, of the t-butyl alcohol?
Samples used: n-butyl alcohol, sec-butyl alcohol, tert-butyl alcohol, acetaldehyde, n-butyraldehyde, benzaldehyde, acetone, acetophenone, isopropyl alcohol Based on the samples used, which alcohol is most readily oxidized? Why d you think this is so?

How to prepare 10% butyl alcohol 3L from butyl alcohol in ml unit
CONTEXT So we did an Sn1 reaction in chem lab to convert t-butyl alcohol to t-butyl chloride by the following reaction C4H10O + HCl --> C4H9Cl + H2O We did this by mixing the HCl and the t-butyl alcohol in a separatory funnel, then we collected the organic layer that formed and vacuum distilled the product. QUESTIONS What is something that could cause a low yield in this experiment? we got a 26% yield, I was thinking maybe heating up...
102 PROPO344: Molecular Mass Determination by Freezing Point Depression in t-Butyl Alcohol 3. A student determined the K of t-butyl alcohol using tap water instead of distilled or deionized water. Describe the problems that might have been encountered. How would these problems affect the magnitude of K?
asap please
thanks

Part II. Competing nucleophiles with t-butyl alcohol 1. The composition of the product mixture is analyzed based on refractive index measurem. At 20.0 °C, the refractive index of puret-butyl chloride is 1.3877 and that of pure 1-buty bromide is 1.4280. One previous student determined the refractive index of his product mixture to be 1.4250 at 20.0 °C. Assume a linear relation between the refractive index and the molar composition of the mixture. Calculate the molar percentages of t-butyl chloride and/-butyl...
