Splet28. apr. 2024 · Chirality (pronounced kie-RAL-it-tee) is the property of handedness. If you attempt to superimpose your right hand on top of your left, the two do not match up in … SpletWhy 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.
