Key Concepts

Organic Reaction Mechanisms

This concept involves understanding the step-by-step pathways by which reactants transform into products. It includes identifying the movement of electrons, the formation and breaking of bonds, and the intermediates that might be formed during various types of reactions such as nucleophilic substitutions, electrophilic additions, or eliminations.

Stereochemistry

Stereochemistry focuses on the three-dimensional arrangement of atoms in molecules. It is crucial for predicting and representing how atoms are oriented in space, which can significantly affect the physical and chemical properties of the compounds. This includes concepts such as chirality, enantiomers, and diastereomers.

Three-Dimensional Representation of Molecules

This concept involves the use of drawing conventions like dashed and wedged bonds to depict the spatial orientation of substituents around a chiral center or within a molecule. These representations help communicate the stereochemical aspects of a molecule clearly and accurately.

Transcript

00:10 This is a halo hydrant formation reaction that means the addition of halogen and oachine when you when you consider the haloidrine formation reaction you have to consider two things the first one the halo hydrant formation reaction is always anti -addition and this reaction is a radio selective let's see the first one to understand the halo hydrogen reaction first let's see the mechanism of the reaction the first step is a five bond electrons is attack on a halogen so we can so in the five electrons attack on the halogen atom the same time this halogen make a bond with the other carbon atom of that alkin in the same time this bond is dissociated to the formation of the halide iron this first step it formed the bridge compound with the halogen atom in the second in the second this is the first step the second step water molecule now the media has halide ions and the water molecules but the concentration of of water molecule is high therefore there's a high possibility of attack of water molecule to this this cation so the second step the loan pair of the electron is attack on the one of the carbon atom and it break the bone to the halogen atom so i'm sorry for this in this example so the water molecule so we the electron pair of the water can attack on either carbon in this example if it's attacked this way and it break the bones like this way when oxygen use electrons to the one electron to the carbon and make a bond it's make a positive charge and when this bond dissociated this way the positive iron on the halogen become neutral so always remember this hallow hydrant formation is an anti -addition reaction because always the water molecules attack by the backside when it's attacked backside so it gives a trans product so halogen is added to the one side of the double bond the water molecule added to the other side it's a anti -edition so this is the this is the second step of the reaction in the third step another water molecule can come and abstract a proton from the positive oxygen atom so this one is come here and abstract a proton in the same time this bond is dissociated to this way and it form ohh bond here so this is the halo hydrant so always remember halogen and oh which groups are attaching the opposite side or anti -addition.

04:11 The next thing you have to consider the halo hydration, hydrant formation is a regio -selective reaction.

04:20 Let's consider cymetric alky...
