www.uou.ac.inThe study of stereochemistry focuses on stereoisomers and spans the entire spectrum of organic, inorganic, biological, physical and especially supramolecular chemistry. Stereochemistry includes method for determining and describing these relationships; the effect on the physical or biological properties.

www.vanderbilt.eduStereochemistry of the SN1 Reaction: it is actually a complicated issue. For the purpose of Chem 220a, sect. 2 the stereochemistry of the SN1 reaction gives racemization. A chiral alkyl halide will undergo SN1 substitution to give a racemic product CH2CH2CH2CH3 Cl H3CH2C H3C H2O CH2CH2CHCH3 H3C H3CH2C Carbocation is achiral OH2 OH2 CH2CH2CH2CH3 ...

med.fau.eduStereochemistry is important because biological systems usually use only one specific isomer of a given compound. II. Types of Biomolecules Biomolecules can be divided into several major classes and a few minor classes. A. Amino Acids and Proteins Amino acids are relatively small molecules with molecular weights around 100-200.
SN1 and SN2 Reactions - Illinois Institute of Technology
web.iit.eduThe S N 2 Reaction Notes: In the SN2 reaction, the nucleophile attacks from the most δ+ region: behind the leaving group. This is called a back-side attack. This back-side attack causes an inversion (study the previous slide): after the leaving group leaves, the other substituents shift to make room for the newly-bonded nucleophile, changing the stereochemistry of the molecule.
