Study Notes
IUPAC Names and Compounds
- The IUPAC name for CH2 = CHCH2Br is not specified.
- Vinyl chloride is commonly known as CH2=CHCl.
- The common name for (CH3)3CBr is tert-Butyl bromide.
Stereochemistry
- The term used to describe the process where configuration has been inverted in a chemical reaction is inversion.
- In SN2 reactions, the reason behind the inverted configuration of the product is that the nucleophile attacks from the back of the leaving group.
- The term used to describe the process where a 50:50 mixture of two compounds is obtained and the product is optically inactive is racemization.
- SN1 reactions of optically active alkyl halides are accompanied by racemization because the intermediate carbocation is planar, allowing the nucleophile to attack from either side with equal probability.
Solvents and Uses
- The major use of dichloromethane (methylene chloride) is as a solvent.
- Exposure to lower levels of methylene chloride in air leads to slightly impaired hearing and vision due to its effect on the nervous system.
- Chloroform is commonly used as a solvent for fats, alkaloids, and other substances.
- Polyhalogen compounds are commonly used for their insecticidal and pesticidal properties.
