Key Concepts

Reaction Mechanisms

This concept involves understanding the step-by-step process by which reactants convert into products. It is crucial for determining how bonds are made and broken during a reaction, which in turn helps predict the structure and configuration of the resulting products.

Stereochemistry

Stereochemistry deals with the spatial arrangement of atoms within molecules and how this arrangement impacts the physical and chemical properties of the compounds. This includes concepts such as chirality, stereoisomers, and the use of wedge-dash notation to depict three-dimensional structures in two-dimensional drawings.

Stereoselectivity and Stereospecificity

These concepts refer to the preferential formation of a specific stereoisomer when multiple outcomes are possible. Stereoselectivity is observed when one stereoisomer is favored over others in a reaction, while stereospecificity means that the mechanism of the reaction uniquely leads to a particular stereoisomer, emphasizing the importance of reaction pathways and molecular orientation.

Transcript

00:01 Draw the products, including the sterochemistry of each reaction.

00:04 All right.

00:05 So we have some mechanisms that we need to draw and just make sure that we are aware of where the sterochemistry is and how we're going.

00:13 All right.

00:13 So first one, hbr and alkyne.

00:17 So this alkyne will donate inward to the most stable carbon.

00:21 One electron goes outwards.

00:23 This h, that h donates both to the br.

00:25 So we then lose our alkyne.

00:30 But we now have a carbocatinine.

00:32 We have a new hydrogen bond that will draw right there just so we know where it is, but we're not going to keep drawing him.

00:39 And we have a negative br who is looking for something.

00:45 So his, we're going to have a electron pair will attack right here at this carbocatin because there's no rearrangements that are favorable for it.

00:54 It's already the most stable it can be at that point.

00:58 So we now have a br group.

01:02 Okay, so now it's important to identify stereochemistry for this.

01:09 Do we have chirocentres that we need to be aware of? we do have a carol center right here.

01:16 All right, so let's go ahead and draw like sterechemistry for this.

01:19 So there is a same addition, and there's anti -edition.

01:23 So let's draw our base structure, start by drawing your base chain.

01:29 There's our base chain.

01:31 So we're going to consider this coming out to the front for hydrogen.

01:38 That's the hydrogen we added...
