Resonance vs. Isomers

Postby Frenz Cabison 1B » Sat Oct 28, 2017 10:29 pm

What is the difference between resonance structures and isomers?

An isomer refers to a molecule with the same molecular formula but different chemical structure, whereas a resonance structure is when more than one Lewis structure can be drawn for the molecule.

The key difference between these two is that different chemical structures is a result of rearranging the atoms, whereas resonance structures are caused by differences in electron arrangement.

Hi!

Resonance structures only differ in structure of electrons. However, isomers differ in structure of electrons and atoms. They are essentially different compounds with the same number of atoms. Examples of isomers include butane and isobutane that you can look up on google if you want

Isomers are molecules that share the similar chemical formulas but their atoms are structured and arranged differently. Consequently, the purpose of these molecules differ as well.

Resonance structures show molecules or ions that have the same chemical formulas as well, but simply different structures, but they still serve the same purpose.

Hope that helps!
