WebIn general, if you have a small molecule with no sp3 centers in the molecule, the molecule is planar. But there are many exceptions. Here are a few common ones: - Water is planar. The oxygen is sp3 but there are only 3 atoms so there's nothing to stick out of the HOH plane. - Allene is not planar. WebChirality is derived from the Greek word χειρ (kheir) that stands for "hand". An object is said to be chiral if the object and its mirror image are non-superimposable, just like our right and left hand. Now you must be wondering what we mean by ‘non-superimposable’.

WebFeb 13, 2024 · Chirality. Chirality essentially means 'mirror-image, non-superimposable molecules', and to say that a molecule is chiral is to say that its mirror image (it must have one) is not the same as it self. Whether a molecule is chiral or achiral depends upon a certain set of overlapping conditions.

WebApr 8, 2024 · Enantiomers. Enantiomers are a pair of molecules that exist in two forms that can not be superimposed on each other but are mirror images of each other. Enantiomers have a Chiral Carbon. A Chiral Carbon is a center of Carbon that is bound to four distinct atoms or groups. The existence of Chiral Carbon is referred to as Chirality (in a molecule). WebAn amino acid has the general formula H₂N-CH (R)-COOH, where R stands for the different acids. Notice that the central C atom is chiral — it has four different groups attached — so the molecule can exist as a pair of enantiomers (nonsuperimposable mirror images). One of these is the D isomer, and the other is L (i.e. a pair of R/S isomers).

WebCis and trans double bonds are sterogenic centers in that two different compounds are possible that are stereoisomers (diasteromers). However, that is not sufficient. You must have two cumulated alkenes (c=c bonds next to each other) with at least 2 substituents to have "axial" chirality. There is also helical chirality.
