Enantiomers are mirror-image molecules that cannot be superimposed; diastereomers are stereoisomers that are not mirror images of each other. Students often swap the terms because both describe 3-D arrangements around chiral centers, yet only enantiomers behave as perfect mirror pairs. Diastereomers feel like “almost the same” molecules, so the names blur in memory. Key Differences…

French vs English Bulldog are two compact, flat-faced breeds that share a bulldog ancestry but differ in size, ear shape, and overall build.

Ferrous Sulphate is an iron salt used to boost low iron stores; Folic Acid is a B-vitamin that helps make healthy red blood cells. They tackle different parts of the same problem.

C1500 is a two-wheel-drive Chevy half-ton pickup; K1500 is its four-wheel-drive twin. The only difference is the drivetrain.

Double Salt is a mixture of two simple salts that crystallize together but separate again when dissolved. Complex Salt is a single compound where metal ions bond to ligands, forming a stable new ion that stays intact in solution.
