    See, if all the chiral centres are being inverted in a molecule i.e if R centre is converting to S and S is getting converted into R, it's enantiomers but, if any single centre has retained its configuration..it will be a diastereomers. Two related stereoisomers if not enantiomers, are diastereomers.

    diastereomers have atleast two chiral centre . have same configuration on one chiral centre and opposite configuration on another chiral centre

    If all of the chiral centers are of opposite R/S configuration between two stereoisomers, they are enantiomers. If at least one, but not all of the chiral centers are opposite between two stereoisomers, they are diastereomers. check this image 👇

    simply you can check by giving R and S Nomenclature ..Ex:-..if RR in one isomers and SS in other isomers and vice versa then they are enantiomers....if RR in one isomers and RS in other then they are diastereomers
