WebDec 17, 2024 · A meso compound contains a plane of symmetry and so is achiral, regardless of whether the molecule has a chiral center. A plane of symmetry is a plane that cuts a molecule in half, yielding two halves that are mirror reflections of each other. By definition, a molecule that's not superimposable on its mirror image is a chiral molecule. WebA chiral molecule is an enantiomer of its mirror image.

WebChirality Center. -Most chiral molecules have a chirality center. -For a molecule to be chiral, it must have an asymettric- an sp3 hybridized carbon atom bonded to four different groups. -The asymmetric carbon is also called a: chiral center or stereocenter. -A molecule with a single chirality center is chiral. 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 ... duneden lodge randalstown
