What is the term used for isomers that have the same constitutional formula but differ in spatial arrangement of atoms?

💡 Solution & Explanation

Stereoisomers are chemical compounds that share the same molecular formula and bonding sequence of atoms but differ exclusively in the three-dimensional spatial orientation of those atoms. Chain and position isomers, by contrast, fall under constitutional isomerism where the connectivity or skeleton of the atoms differs. This spatial variation often leads to distinct biological and chemical properties among pharmaceutical compounds.
