Ephedrine, a stimulant and illegal drug is an … WebWhy does carbon Show chirality? This important type of stereoisomer occurs because carbon sp 3 tetrahedral centers can allow a molecule to show chirality. Chirality exists when the mirror image reflection of a configuration at an sp 3-hybridized center cannot be exactly superimposed, or placed to match exactly, on the original.
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). WebQuestion.
