Conversation

I was reading about chemistry, and I learned about cis isomers today.

Oh really? That sounds interesting! What does it mean?

It describes a molecular structure where certain groups are on the same side of a double bond, like in cis butenedioic acid.

Got it! That definitely makes sense and is crucial for understanding organic compounds.
