Definition 1 of 1
Pro Tip 1/3Chemistry Term
The word 'isomeric' is frequently used in chemistry to discuss molecules with the same atoms but arranged differently. 
Isomeric structures can drastically change the properties of a molecule.
Pro Tip 2/3Non-Interchangeable
'Isomeric' refers to unique molecular shapes, so it's not interchangeable with terms for identical compounds. 
Despite having the same formula, isomeric molecules are not the same compound.
Pro Tip 3/3No Visual Imagery
The term 'isomeric' doesn't convey a specific shape; the detailed structure must be examined separately. 
Knowing a substance is isomeric tells you nothing about its appearance.
