Optically active in chemistry
WebMeso Compound is Optically Active. A non-optically active member of a collection of stereoisomers, of which at least two are optically active, is known as a meso compound or meso isomer. This means that despite having two or more stereogenic centres, the molecule is not chiral. They’re achiral compounds, meaning they feature several chiral ...
