What is the chemical formula of Ferrocene?
chemical symbol for ferritin
How many C13-NMR signals would you expect to see in acetylferrocene?
there will be three peaks. one for the carbons in ferrocene around 70 -75. one for the carbonyl carbon (around 200) and one for the methyl group in acetyl (around alkyl region).
How do you check a reference electrode?
Measure a cyclic voltammogram (CV) of a well-characterized compound, such as ferrocene, whose reduction potential is very well known. If the potential you measure matches the literature value, then your reference electrode is fine. If it does not, then you can determine how far off it is from the difference of where the peaks in the CV should be compared to where you measured them.
How many substances sublime?
Only some substances sublime because of pressure. Some solids have a high enough vapor pressure and triple point that makes them sublime in the air, which may be easier than evaporating.
Do all solids turn into liquids?
No. By example Iodine (I2) will directly 'evaporate' to gas at STP. This is called sublimation, which occurs at temperatures and pressures below a substance's triple point. Other compounds like this: carbon dioxide (dry ice), naphtalene, ferrocene
Why ferrocene is organomatallic compound?
Ferrocene is an organometallic compound because it has two rings of cyclopentadienyl on opposite sides of a metal atom.

What is the structure of the intermediate species that attacks ferrocene to form acetylferrocene?
acylium ion
Which one is more polar ferrocene or fluorenone?
Fluorenone is more polar than ferrocene.Ferrocene is non-polar due to its symmetry.
Why does Fe have a higher melting point than CCl4?
since acetyl ferrocene is attached to an acetyl group, the upper ring is asymmetrical. unlike ferrocene, whose rings are symmetrical (no attached groups) the melting point is higher due to symmetry. aka higher symmetry = higher melting point
What is the reaction mechanism for the synthesis of formyl ferrocene with triethyl orthoformate and AlCl3?
it's a friedel-craft acylation with the triethyl orthoformate being a formyl synthon. the AlCl3 is a Lewis acid, it coordinates the ethoxy group, which is kicked off by the adjacent oxygen. The ferrocene then is the nucleophile and the rest of the reaction is a standard electrophilic aromatic substitution leaving the formyl oxonium, which is quenched to the formyl on work-up. i think that's how it goes anyway, i haven't read the paper.
What is redox mediator?
A redox mediator is a hyperbranched polymer having redox moieties (e.g. ferrocene) incorporated into its structure and/or chemically bonded to its periphery. It is attached to an electrode and assists in transferring electrons between the electrode and a redox enzyme.
How many C13-NMR signals would you expect to see in acetylferrocene?
there will be three peaks. one for the carbons in ferrocene around 70 -75. one for the carbonyl carbon (around 200) and one for the methyl group in acetyl (around alkyl region).
