Chiral class 12
WebCan someone tell me if a C-atom can still be Chiral when he has 3 different groups and one is double-bonded? For example: 1-bromo-1,2-dichloroethylene • ( 3 votes) dysmnemonic 10 years ago No; a C atom needs to have four different groups bonded to it to be chiral. In that example, the molecule will instead have E/Z isomerism across the double bond. WebJun 24, 2024 · Definition of Chiral: Chiral is a term that is used to describe an object or item that is not completely and identically superimposable with a mirror object of itself. Chirality is a feature that is often used in chemistry to describe the configuration of atoms of molecular structures. Symmetry of Chiral:

Web12 years ago Chiral molecules have different properties. This one time there was a drug called Thalidomide which was made and it was to cure morning sickness. However, the other form of it, the other chiral form, was a drug that caused birth defects. It was found to be seriously teratogenic. The word chiral emanates from the Greek word cheir, which means hand. A molecule or ion is chiral if it is non-superimposable, i.e. it can not be superimposed on its mirror image. This geometric property of a molecule is called chirality. 1.
