We now know that chiral molecules contain one or more chiral centers, which are almost always tetrahedral (sp3-hybridized) carbons with four different substituents.
WebFormulas having no chiral centers are necessarily achiral. Formulas having one chiral center are always chiral; and if two or more chiral centers are present in a given structure it is likely to be chiral, but in special cases, to be discussed later, may … WebMay 13, 2015 · 5. Take a look at your carbon circled in red, it has a hydrogen on it giving it four different groups. Now look at the C circled in blue. There is no hydrogen attached to that carbon because it already has four bonds (two to the O, one to the OH, and one to the rest of the molecule.) Therefore it only has three substituent groups attached and ...
