L-alanine and D-alanine are enantiomers:
In[1]:=

Out[1]=
True
But trans- and cis-1,2-dichlorocyclohexane are not:
In[2]:=
{m1,m2}={Molecule["trans-1,2-dichlorocyclohexane"],Molecule["cis-1,2-dichlorocyclohexane"]}

Start with a molecule and generate its mirror image programmatically:
In[1]:=
m1=Molecule
;m2=MoleculeModify[m1,{"TransformAtomCoordinates",ReflectionTransform[{0,0,1}]}];MoleculePlot3D/@{m1,m2}
|  |
|
Out[1]=
,
These two molecules are mirror images and chiral, so they are enantiomers:
In[2]:=
| EnantiomersQ |
Out[2]=
True
A non-chiral molecule is not an enantiomer with its mirror image:
In[3]:=
| EnantiomersQ |
Out[3]=
False
