Stereoisomers are: molecules that are coiled into compact and spherical shapes molecules that release heat and have negative enthalpy changes molecules with the same molecular formula but differ in the way their atoms are connected . molecules with the same chemical bonds and formula but have a different geometry

Stereoisomers are Molecules with the same chemical bonds and formula but different geometry

Explanation:

Stereoisomerism is a term that refers to a form of Isomerism, where the atoms that make the molecule are bonded in the same order, but with a different geometry. In the case of Organic Chemistry, this means that the functional groups when comparing the molecules do not change. Whereas Constitutional Isomers are molecules that share the same molecular formula  but differ in the way their atoms are connected. In terms of Organic Chemistry this would mean the molecules have different functional groups.

i had this on my unit activity, i can you if you are a plato student. are you a plato student?
