Definition

Relating to compounds that have the same molecular formula but differ in the arrangement of atoms in space.

Example

Stereoisomeric compounds can have very different properties despite having the same chemical formula.

Conversation

Have you heard about the new chemistry project we're doing?

Yeah, I heard it's focused on stereoisomeric compounds.

Exactly! I think it's fascinating how they can have the same formula but different structures.

Right? It's amazing how that affects their properties.

Root Explanation

Stereoisomeric → It is formed from "stereo-" (from Greek "stereos", meaning solid or three-dimensional) and "isomeric" (from Greek "isomerēs", meaning having the same measure or part). The word describes compounds that have the same molecular formula but differ in the arrangement of atoms in three-dimensional space.

Memory Tip

Think of 'stereo' meaning three-dimensional and 'isomeric' referring to having the same parts — this helps you remember that stereoisomeric relates to substances that are the same in composition but differ in their three-dimensional arrangement.
