if you find R and S,
one is S,S and one is S,R👍

in a compound with two chiral centers, changing the sterochemistry at 1 chiral center results in diastereomers
structural isomers have same molecular formula, but different connectivity. these two compounds have same connectivity. hope this helps!

Can someone please explain to me how the structures in #81 are
Diastereomers? I thought they were structural isomers.....

Molecule on the left: from left to right : Two asymmetric centers, with configuration of S, S
Molecule on the right: from left to right : Two asymmetric centers,with configuration of S, R
Diastereomers have one asymmetric center same, the other one different ( asymmetric carbon on the left maintains S on both molecules, while asymmetric carbons on the right have opposite configuration).
