Acetylation of ferrocene and column chromatography
Lab 4: Question 3 Homework • Unanswered Important ... The solvent is changed from petroleum ether to diethyl ether after the ferrocene is collected from the column. Why not use diethyl ether the entire time? Because diethyl ether is more polar than petroleum ether Because petroleum ether selectively elutes ferrocene since it contains more ether oxygens than diethyl ether Because diethyl ether would lead to a poorer separation of ferrocene and acetylferrocene Both a...

Question 2 Consider the following estimated equation where sleep is the total weekly minutes spent sleeping, age is a person's age, female is a dummy variable that takes the value of 1 if the person is a female and 0 otherwise, and student is a dummy variable that takes the value of 1 if the person is a student and 0 otherwise. Standard errors are in parentheses. sleep = 1.47 - 2.52 age + 0.18 age? +0.721 female - 1.005...
