Figuring out diastereomers

[hellomister]

I have a question, is there a way to determine if two things are diastereomers by looking at their R/S configurations at the asymmetric atoms? Because so far I have been just rotating molecules in my head and it is very slow. ty.

Yes, you can if know how to determine S and R configurations. Look at definitions for diastereomers and enanthiomers again.

haha thanks! helped a lot!

Yes, the way I figure out if two compounds are diastereomers is if they both have identical stereochemistry except for one of the stereocenters.
