An experiment of synthesising ferrocene using potassium hydroxide and 1,2-dimethoxyethane reacted with freshly cracked cyclopentadiene was carried out. Before the addition of a solution containing iron(II) chloride tetrahydrate in DMSO to the first solution, the solution in the round bottom flask had greatly reduced in volume and had turned red in colour before adding any of the iron(II) chloride tetrahydrate in DMSO. What could be the possible reason for this? Explain why this had happened in detail. NOTE: The total yield was very low of ferrocene product.

a sample was dissolved in water resulting in a clear colorless solution. Addition of HNO3 and AgNO3resulted in a wispy white ppt. Upon treatment with ammonia the white solid dissolved and when HNO3 was added the white solid reappeared. A new sample was prepared. To this sample HCl and cyclohexane were added. NaOCl was added and the sample was mixed. After waiting a few minutes, the sample was clear and colorless. A) HCl and BaCl2 were added resulting in a clear colorless solution.

A task is assigned to an undergraduate student to test two samples (known as compounds K and L) in the laboratory. She placed these two compounds through various scientific tests. She discovered that these compounds have the same molecular formula, C8H8O. When treated with 2,4-dinitrophenylhydrazine, all of these compounds produce brightly coloured precipitate, and both are reduced to an organic compound with the molecular formula C8H10O. However, compound K can be easily oxidized by chromic acid to formed compound N and vice versa for compound L. Furthermore, when both compounds reach with Fehling's solutions, they produce negative results. However, only compound K forms a silver mirror when it reacts with Tollen's reagent, and compound L does not. Identify the possible formulae for compounds K, L, and N by ignoring their possible isomerism. Indicate the formation of compound N from compound K. Predict the chemical reaction that occurs when compound L reacts with…
Organotin compounds play a significant role in diverse industrial applications. They have been used as plastic stabilizers and as pesticides or fungicides. One method used to prepare simple tetraalkylstannanes is the controlled direct reaction of liquid tin(IV) chloride with highly reactive trialkylaluminum compounds, such as liquid triethylaluminum (Al(C2H5)3). 3SnCl4 + 4AI(C2H5)3 →3Sn(C2H5)4 + 4AlCl3 In one experiment, 0.160 L of SnCl4 (d = 2.226 g/mL) was treated with 0.346 L of triethylaluminum (Al(C2H5)3): d = 0.835 g/mL). What is the theoretical yield in this experiment (mass of tetraethylstannane, Sn(C2H5)4)? If 0.257 L of tetraethylstannane (d= 1.187 g/mL) were actually isolated in this experiment, what was the percent yield?
