Detailed Solution
Download Solution PDFThe correct answer is CH3COCH3 and C2H5COCH3
Key Points
- CH3COCH3
- Acetone is an organic compound that is very flammable. This organic solvent is also known as propanone and has the chemical formula C3H6O.
- It is present in vehicle, plant, tree, and forest fire exhaust. It is also found in the human body, typically in the form of blood and urine.
- It has no color and is volatile. It can be dissolved in water, ether, or ethanol, and it has an unpleasant, floral, or pungent scent. As a solvent and antiseptic, it is widely used.
- Acetone was first made by alchemists. Dry distillation of metal acetates is used to make it. At the moment, propylene can either directly or indirectly produce acetone.
- The cumene process produces nearly 83% of acetone. Acetone can also be made in other, more traditional ways.
- C2H5COCH3
- 2-Butanone, also known as METHYL ETHYL KETONE, is the above-mentioned compound. Its molecular mass, C2H5COCH3, is 72.1057 g/mol.
- Methyl ethyl ketone is a colorless, relatively volatile liquid with a pleasant, pungent odor.
- 20°F flash point, heavier than air vapors.
- It is stable during normal transportation and does not react with water or many common substances.
- It affects the throat, eyes, and nose. Toxic substances may result from combustion.
- Butanone is a naturally occurring product. It is produced by some trees and can be found in trace amounts in some fruits and vegetables.
- Additionally, vehicle and truck exhausts release it into the air.
Additional Information
- Homologous series
- A homologous series is a group of compounds that share similar chemical properties and functional groups that differ from the next member by CH2.
- In organic compounds with the same general formula, carbon chains of varying lengths have been observed.
- The homologous series members all belong to the same functional group.
- All members use the same general formula.
- Because they belong to the same functional group, their chemical properties are nearly identical.
- There is a common method of preparation among members.
