Explanation

Stereoisomers are not constitutional isomers because they have their constituent atoms conncented in the same sequence. They differ only in arrangement of their atoms in space.
Thus isomers having same bond connectivities are called stereoisomers. This phenomenon is known as stereoisomerism. The part of chemistry that deals with the properties of stereoisomers is called stereochemistry.
