Acetone absorbs at mas 279 um in hexane but at
max 264.5hm in water.
Answers
Answer:
Hund's rule of maximum multiplicity is a rule based on observation of atomic spectra, which is used to predict the ground state of an atom or molecule with one or more open electronic shells.
Answer:
Acetone has a higher solubility in hexane than in water, which means that it is more readily dissolved in the hexane. The reason for this is because hexane is a non-polar solvent, meaning that it does not have any polar groups or hydrogen bonding.
This means that the molecules of hexane do not interact with the molecules of acetone, allowing them to remain in solution. On the other hand, water is a polar solvent, meaning that it does contain polar groups and hydrogen bonding. This makes it more likely for the acetone molecules to interact with the water molecules, thus reducing the solubility of the acetone in the water.
This is why the wavelength of the absorption peak for acetone is higher in hexane than in water, as the higher solubility in the hexane allows for a greater amount of acetone molecules to absorb the light at the given wavelength.
On the other hand, Hund's rule states that electrons in an atom want to remain unpaired unless they have to pair up to maintain the lowest possible energy level. In hexane, the carbon atoms are surrounded by six hydrogen atoms. This allows the electrons to remain unpaired and move freely around the surrounding atoms, thus resulting in a higher absorption of acetone at 279 μm in hexane.
On the other hand, in water, the oxygen atom has two lone pairs that take up the space around the carbon atom, resulting in forced pairing of the electrons between the carbon and oxygen atoms. This results in a lower absorption of acetone at 264.5 μm in water.
