are Caucasian Asian? I don’t believe Caucasian are Asian but someone said they are and we’re kind of arguing… but correct me if I’m wrong. If they are Asian please explain how.

Asian speaking here and I believe if you are Caucasian, you’re white.

Ifound the exercise on the internet. attached is the list mentioned above.in order for a compound to be considered optically active it can't have any axis or plan of symmetry. the molecule  shouldn't also  be superimposable on its mirror image.with such considerations, the compounds that are optically active are: -third compound on the first image is optically active; -second and third compound from the second image are optically actives.
