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 … WebTherefore, lack of such a plane indicates a molecule is chiral. Compounds that contain a single stereo-center are always chiral. Some compounds that contain two or more stereocenters are achiral because of the symmetry of the relationship between the stereocenters. The prefix "en-" often means "to make, or cause to be," as in "endanger."

WebBut, he shows that when the molecule is rotated, it is still the same molecule. That's why even with the chiral ATOMS, the molecule itself is achiral. You'll see in later videos that this is what is called a meso compound - molecules that have both chiral atoms and a plane of symmetry. A plane of symmetry renders a molecule achiral.

WebHere are two examples of molecules with differing chirality, achiral and chiral. A chiral molecule is distinguished by the presence of two atoms of the same element. If one creates a bisecting plane through the other two atoms, the images on either side are the same. on royalWebNo; a C atom needs to have four different groups bonded to it to be chiral.
