What effect would using a more polar mobile phase in column chromatography have? How would the purity of acetylferrocene be affected by starting with a mobile phase of ethyl acetate instead of hexane? In what wa
Why can hexanes be used to elute the unreacted ferrocene? Why does acetylferrocene not move down the column along with ferrocene? What are the polar and non-polar portions of each of the following lipids? a) Triacyglycerol b) Sphingolipid c) Cholest...
Explain why the reaction occurs or why there is NR for magnesium with chromium (III) chlorate. An experiment on the acetylation of ferrocene is performed, but no acetylferrocene was actually produced. What are some reasons for that? Explain why either greatly decreasing or increa...
Explain the order of elution of ferrocene, acetylferrocene, and why diacetylferrocene is retained by the column at the top. This was column chromatography. In gas chromatography (G.C.), what is the purpose of injecting the sample onto a heated block? When separating a mix...
What effect would using a more polar mobile phase in column chromatography have? How would the purity of acetylferrocene be affected by starting with a mobile phase of ethyl acetate instead of hexane? If a substance has a large Rf value, what does it tell you about the attraction of the...
Suggest how the ester might be separated from any unreacted ethanoic acid or methanol. How many possible isomers could expect for diacetylferrocene? Calculate the volume of 3 M aqueous sodium hydroxide needed to neutralize the acetic acid phosphoric acids in the synthesis of acetylferrocene. Wh...
- hexane-acetone mixture Thin-Layer Chromatography (TLC): Thin-layer chromatography is a chromatic technique that is used to separate the organic mixtures or non-volatile substances. This is a very simple, quick and easy method to separate the o...
Answer and Explanation: The relationship between the molecules isD. Enantiomers. Given that the connectivity of each atom is the same, we can rule out constitutional...
Why does the second acetyl group enter the unoccupied ring to form diacetylferrocene? What is the major product formed on the mono-nitration of phenylacetate? What triggers the immune response? a) Presence of antibodies b) Presence of a f...
This question was from a Chromatography chemistry lab where we separated ferrocene and acetylferrocene using EtOAc and hexanes as the solvent. Based on your general understanding of organic chemistry, Rubbing alcohol is a commonly used disinfectant and has a cooli...
