Confusion on enantiomers and meso compounds Question: Are these compounds enantiomers?



Attempt: The compounds given are mirror images. But if I rotated the three bonds in the third carbon (configuration will not change), I will get a meso compound (plane of symmetry) :


So are these compounds enantiomers or meso compounds?
You are right, the 2 structures are equivalent and the substance has a plane of symmetry and is a meso compound. When in doubt, make a 3D model if possible.
