WebCarbohydrates have one or more chiral centers- carbons with 4 different groups attached, giving rise to the possibility of stereoisomers Generally, a compound containing “n” chiral centers can maximally have 2 “n” stereoisomers. Enantiomers are stereoisomeric compounds whose structures are nonsuperimposible mirror images of each other. WebFrom this definition, D-ribose has four chiral centers, which are boxed in the structure above. The extracyclic carbon is not chiral because it has two hydrogen atoms attached to it. Therefore, there are four chiral centers in D-ribose. Chapter 25, Problem 20P is solved. View this answer View a sample solution Step 2 of 3 Step 3 of 3 Back to top
