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.

Realistically for compounds with more than 1 chiral centre, fisher projection is require to determine if compound is mesoisomer or enantiomers. If someone draws like that then dont rotate carbons to avoid confusion and just assume if it is meso or enantiomers based on diagram alone.
