How would I make Propanone from Propan-2-ol?Propanone is more commonly known as Acetone. Acetone is mostly used to clean surfaces with it. Acetone is easily mixed with water. This is why it makes cleaning so easily. Acetone is used frequently in different lab experiments in organic chemistry.Some of the items that contain propanone are paint thinner and nail polish. Even though it seems that this compound is dangerous, it actually is made in the human body. Acetone can’t be seen and is quite flammable. Propan 2-ol is also known as Isopropyl alcohol.This has many similarities to propane including being colorless and it will catch fire easily. Also, to turn Propan-2-ol to Propanone, one would use potassium dichromate. Then you would dilute H2SO4 and then heat and distill it.

What was the Vital force theory and how did organic chemistry replace it?What was the Vital force theory and how did organic chemistry replace it?The vital force theory was put forward by Swedish chemist BERZELIUS in 1815. According to this theory, organic compounds could be produced only under the influence of some mysterious force existing in living organisms. This mysterious force was called vital force. Since such a mysterious force cannot be created artificially, it is impossible to synthesize organic compounds in the synthesize organic compounds in the laboratory.Organic chemistry is the subdiscipline for the scientific research of structure, properties, and the reaction of organic compounds and organic materials. Before the nineteenth century, chemists believed that compounds obtained from living organisms were endowed with a vital force that distinguished then from inorganic compounds. According to the abstraction of vitalism, organic matter was endowed with a “vital force.”
Why are lattices so important in organic chemistry?Why are lattices so important in organic chemistry?A lattice is essential in organic chemistry because lattices utilize a regular arrangement of particles. These particles include atoms, ions, or molecule. When a substance is in its solid state, as a solid phase material, its particles are arranged to achieve minimum stored energy — the bonding of lattices. Ions are bonded, creating a giant molecular mesh.Molecules are attached with covalent bonding and intermolecular bonding, which forms an atomic lattice. Lattices are arranged to achieve minimum stored energy. Lattice energy is relevant to many practical properties including solubility, hardness, and volatility.
