Diastereomers

Diastereomers is stereoisomers that the mirror image are superimposable.
Molecules or objects that is superimposable on its mirror images is said to be achiral. Achiral molecules contain a plane of symmetry. All achiral substances are optically inactive.

Enantiomers

Now, we're going to explain a little bit about enantiomers. Enantiomers is one type of stereoisomers. Enantiomers is stereoisomers that the mirror images are not superimposable. Enantio in Greek means opposite.

Molecules or objects that is not superimposable on its mirror image is said to be chiral.

Our Main Focus In This Topic

We decided to choose stereoisomers as our main focus in this topic and as our project for Chemistry(SK027) because many students including us are facing some difficulties and become confuse when we have to differentiate between enantiomers and diastereomers. Both are types of stereoisomers. We decided to choose this subtopic because we want to help students out there especially our friends in order to understand this subtopic better.

What Is Isomers?

Isomers is compounds that have same molecular formula but differ in the way the atoms are arranged. It comes from Greek words, isos+meros which give meaning made of the same part.

There are two types of isomers which are constitutional isomers that are different in connectivity and another one is stereoisomers that have same connectivity but different arrangement in space.
