Erythreo enantiomers are stereoisomers with two adjacent chirality centers, which have two similar groups on the same side of the carbon chain, and threo enantiomers have the two similar groups on opposite sides of the carbon chain.
Constitutional Isomers are compounds which differ in their connectivity.Theyhave the same Molecular Formula but differ in the way the atoms are connected in three dimensional space
Nuclear isomers are nothing but chain isomers

Epimers are a pair of stereoisomers with more than one chiral centre which differ in chirality at one and only one chiral centre
