[AdaAda87]

yes if the compound is meso, then it wont be optically active. Meso = a line of symetry.

I see one question from Kaplan. This one is not meso and chiral, but it was not optically active.

Maybe it was a racemic mixture.

racemic mixture is not optically active?

isn't racimic mixture consisted of R and S?

 

[PreDent2009]

To be more specific, a racemate is a molecule that has equal amounts of R and S. Therefore, the R will rotate polarized light lets say at an alpha bracket of 15, while S will rotate it at exactly an alpha bracket of -15, hence showing no optical activity.
