Column Chromatography of 9-Fluorenone ExperimentIntroduction:Column chromatography is an important chromatography method used to separate and purifyorganic compounds. Column chromatography is typically used to separate impurities and purifyproducts from chemical reactions, including separating unused starting material from products.Column chromatography is very similar to Thin Layer Chromatography (TLC) because it relies on asolid stationary phase (absorbent) and liquid mobile phase (eluant) to separate organic compoundsbased on their different polarities.In column chromatography, the stationary phase is a solidabsorbent, typically silica gel or alumina, with a liquid coatingpacked into a glass column. The stationary phase is typically verypolar. An eluant (mobile phase) solvent travels down the columnand the separation occurs as the organic compounds enter intoequilibria with the stationary and mobile phases. The polarity of theeluant may be adjusted from non-polar solvents, such as hexanes orpetroleum ether, to very polar dichloromethane or ethyl acetate;mixtures of hexanes and ethyl acetate are typically used to finelytune the polarity of the eluant as needed for each separation.-Solvent: Entire column must alwaysbe under solvent-Sand (1 cm)Alumina: 25 g for every 1gof mixture tobe separated-Sand (1 em)Glass wool or cottonStopcock to control flowAs in TLC, non-polar compounds are not attracted to the polarstationary phase and travel easily down a column with a non-polareluant. By contrast, polar compounds are attracted to the polarstationary phase and will require an eluant with more polarity totravel down the column. As the organic compounds elute from thecolumn, they are collected in flasks or test tubes as dissolved material in the eluant, this is called afraction. It is recommended to always test each fraction by TLC to confirm the identity of theorganic compound and ensure that no other compounds are in that fraction.Collection flaskOnce a compound has been eluted from the column, simple evaporation of the eluant allows for therecovery of the purified organic compound.Add aluminaAdd Eluent Add EluentAdd EluentAdd EluentAdd compoundThen "pack;CollectCollectcompound I compound 2 In this experiment, the eluant is?1)petroleum etherO 2) water3) dichloromethane4) ethyl acetate

I know you don't answer graded questions and I am not looking for you to straight up give me the answer to this but how do I even start? like I said before I know that the highest peak is 16amu which is Oxygen but do I just the vertical bar as a ratio? Like the next bar to the left (15amu?) is like 90% intensity? so like 9:10 ratio? There isn't even a 15amu element so please just give me some idea where to start. The place in the book it tells you to go to read has nothing about this stuff, its about finding empirical formulas from mass or percentages.... please help me!
