What are diastereomers give example?

Diastereomers may often include compounds which are ring structures. Imagine, for example, two compounds with a six-membered ring, each with two substituents, a chlorine atom and an ethyl group. They are also not mirror images of each other, just like our previous example, which defines them as diastereomers.

What is Topicity of ligand?

Ligands are heterotopic and called as enantiotopic because by the substitution of the ligands by other ligands gives pair of enantiomer. Two ligands are enantiotopic if replacement of either one of them by a different achiral ligand gives rise to enantiomeric products.

What are Enantiotopic faces?

Enantiotopic faces, atoms or groups look the same on their own, but will react differently with chiral molecules. Diastereotopic faces, atoms or groups always appear different.

What are Homotopic ligands?

Like ligands in an organic molecule that are equivalent (see equivalent ligands) under all conditions are said to be homotopic. Molecules 2 and 3 are superimposable on each other, meaning that they are identical. Identical molecules have identical chemical properties under all conditions.

What are examples of topicity in organic chemistry?

With these multiple-choice questions, you’ll be assessed on topics like the relationship between hydrogen atoms in a methane molecule and the outcome of replacing hydrogens with a generic atom X in a given molecule. For more on atoms and molecules, you can read the lesson called Topicity in Stereochemistry: Relationships & Examples.

How is topicity related to the structure of substituents?

In stereochemistry, topicity is the stereochemical relationship between substituents and the structure to which they are attached. Depending on the relationship, such groups can be heterotopic, homotopic, enantiotopic, or diastereotopic .

Which is the correct definition of topicity in stereochemistry?

Topicity. In stereochemistry, topicity is the stereochemical relationship between substituents and the structure to which they are attached. Depending on the relationship, such groups can be heterotopic, homotopic, enantiotopic, or diastereotopic .

Which is the best definition of topicality in a debate?

What is Topicality? Topicality (T) is an argument debating whether or not the affirmative’s plan follows the resolution. The negative team can use this argument to prove that the affirmative’s plan promotes definitions of words in the resolution are incorrect or not good enough.
