Definition

A type of isomerism that occurs when molecules have the same chemical formula but differ in the arrangement of their atoms in space.

Example

Stereoisomerism is important in chemistry because it can affect the properties and reactions of molecules.

Conversation

Have you ever heard of stereoisomerism?

Yeah, I think it's about how molecules can be arranged differently in space, right?

Exactly! It's fascinating how that affects their properties.

I know, right? It really shows how complex chemistry can be.

Root Explanation

Stereoisomerism → It is formed from "stereo-" (from Greek "stereos", meaning solid or three-dimensional) and "isomerism" (from Greek "isos", meaning equal, and "meros", meaning part). The term describes a phenomenon where compounds have the same molecular formula but differ in the spatial arrangement of atoms, thus creating different three-dimensional structures.

Memory Tip

Think of 'solid' ('stereo-') shapes that are 'equal parts' ('isomerism') but arranged differently in space — that's what stereoisomerism means.
