Does $\ce{MA3B2C}$ type have optical isomerism or just geometric isomerism? I was told that it has three isomers, two cis and one trans. Are the two cis isomers optically active?

$\begingroup$ well i worked out that for the two cis isomers, 'b' could be trans to 'a' or 'c' , and they would be different because of the difference in arrangement, but what I cant figure out is if they're optical isomers of each other, because when I take one of the cis isomers which is 'b' being trans to 'a' and draw its mirror image and rotate it I'm not able to bring 'b' trans to 'c' , but its mirror image does seem to be non-superimposable $\endgroup$– notsoanonpersonCommented Apr 16, 2021 at 8:00

1$\begingroup$ Don't draw mirror images, better look for a symmetry plane in the molecule, because it is there. $\endgroup$– Ivan NeretinCommented Apr 16, 2021 at 8:50
