我想問係吾係有chiral centre就optically inactive 冇就active
有internal plane of symmetry就active 冇就inactive

Evidence of enantiomer,

1) the isomer is non-superimposable with its "mirror image" form
2) the isomer has no internal plane of symmetry
3) the two isomers can rotate the plane of polarization of the plane-polarized light into opposite spin (that's why we also call them optical isomer)

Note that if the enantiomer is maded up of 4 different groups with a central carbon, we called that carbon chiral centre.
