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. WebIllustrated Glossary of Organic Chemistry. Stereocenter ( chiral center): An atom with three or more different attachments, interchanging of two of these attachments leads to another stereoisomer . Most commonly, but not …
