considering the structure of ferrocene and acetylferrocene, identify what interparticle/intermolecular forces are present between these ferrocenes and the immobile phase. How do these IPF/IMF's help explain the ORDER in which the ferrocenes come off the alumina column?
Homework Answers
1) acetylferrocene contains polar (C=O) group .hence, there exist dipole dipole interaction between acetyl ferrocene and polar Alumina column.
on the other hand, weak vanderwall forces exist between ferrocene and Alumina column.
stationary phase in case of Alumina column is Polar.
2) as both, acetyl ferrocene and Alumina (stationary phase) is Polar, so strong intermolecular interaction takes place between them. so acetyl ferrocene is strongly absorbed on the surface of column. while, due to weak interaction of ferrocene it comes out first.
So, the correct order of coming from the column is;
first ferrocene will come followed by acetylferrocene.

These questions are from an experiment where we had a mixture of Ferrocene, acetylferrocene and diacetyl ferrocene and we separated each by using column chromatography. Before doing the column chromatography we did TLC analysis to ensure that we did, in fact, have a mixture of these 3 compounds. During the column chromatography we first eluted the ferrocene using pure hexane. Then we eluted the acetylferrocene using a 1:1 mixture of hexane and methylene chloride. Then we eluted the diacetylferrocene using...

This is regarding intermolecular forces. Which is the only type of intermolecular force present between molecules of hydrogen (H2)? Is it covalent bond, dipole-dipole forces, hydrogen bond, or dispersion forces? Which of the following is an intermolecular force? Is it covalent bond, ionic bond, metallic bond, or hydrogen bond? Also, rank these 4 forces in order from weakest to strongest: Disperson forces, Dipole-dipole forces, hydrogen bonds, Chemical bonds

The Rf value in this experiment is a function of the intermolecular forces present between the eluent, the paper, and the molecule being carried along. Intermolecular forces are essentially a measure of how "attracted" two molecules are to each other. If a dye has a low Rf value, is it more attracted to the eluent or the paper? What about if it has a large Rf value? Explain.

Intermolecular forces (IMPs) are the forces of attraction (or sometimes repulsion) that act between neighboring molecules All IMPs are based on etectrostatic interaction and are relatively weak compared to the Intramolecular forces that hold the atoms within a molecular together. In today, workshop you will practice to identify IMFs and predict their effect on boiling point melting point, vapor pressure and enthalpy of vaporisation (Delta Hvap). The Delta Hvap for a given molecule is the energy required to transform a...
