Mesocompound

In a mesocompound, half of the molecule is the mirror image of the other half. As a result,one chirality centre will rotate the plane of polarised light in one direction andthe other chirality centre will cancel that direction by rotating the polarised in the other direction by the same amount. Hence the resultant roation is zero and meso compounds do not rotate the plane polarised light.

(Concept of stereoisomerism)
