How does the shape of a compound influence its function?

Different shapes do different functions.

What are geometric isomers?

Same formula, different arrangement around a double bond

What is an enantiomer?

A mirror image, seen in Organic Chemistry

What's the difference between the empirical and molecular formula?

an atom/group that always reacts in a certain way in an organic molecule

What are the 3 types of Isomers?

Structural, Geometric and Enantimers

what happened in the thalidomide tragedy?

thalidomide caused limb malformations in new borns
