1) Order the compounds based on their affinity for the stationary phase typically used in column or thin layer chromatography:
Highest affinity to lowest affinity:
Alcohols
Ethers
Hydrocarbons
Ions
2) How many molecules of biodiesel are produced for each molecule of vegetable oil?
Homework Answers
In normal TLC, stationary phase is polar , sillica gel is mainly used in stationary phase.
hence polar substance has higher affinity towards stationary phase.
polarity order of the compounds
Hydrocarbons < Ether < alcohols < ions.
hence affinity order also follows the same order,
from highest to lowest order is
ions> alcohols> ether > hydrocarbons
2.
3 molecules of biodiesel are formed by one molecule of vegetable oil.

Background In this lab, we are going to learn how to use a powerful separation technique called chromatography which can separate compounds that are quite similar to one another. Chromatography is a general type of separation in which a mixture of compounds passes through a stationary phase. Different compounds have different relative affinities for the mixture traveling along the stationary phase, or the mobile phase, and the stationary phase, causing these compounds to separate from one another. More specifically, we’re...

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...

Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...
