WebIf a molecule has more than one chiral carbon, then it will have more than one pair of enantiomers. The number of stereoisomers that a molecule has can be calculated from the number of chiral carbons. If a monosaccharide has "n" chiral carbons, then it will have 2 stereoisomers. QUESTION: How many stereoisomers are possible for each of the ... WebThe rule of thumb is: chiral carbon centers are carbon atoms that are attached to four different substituents, that are placed at the corners of a tetrahedron. Chiral carbon atoms are also referred to as ‘stereogenic carbons’ or ‘asymmetrical carbon atoms’. Compound 1 …

WebNov 25, 2015 · 1 Answer Truong-Son N. Nov 25, 2015 Since for every atom that can exist in more than one configuration, you have R or S ( sp3 ), or E or Z ( sp2 ), you have two configurations for each of those atoms. If you had 2 of those atoms, then you have 4 configuration combinations: ( R, R ), ( R, S ), ( S, R ), ( S, S ). WebA good rule of thumb is that a chiral carbon has four distinct substituents (you can't have more than four anyway). This structure has no such carbon: every carbon has at least two hydrogen atoms attached. None is chiral. b) 3-pentanol: This one has none either. WebPossible Answers: Three Four Two Five One Correct answer: Two Explanation: A stereocenter exists when the central atom is bound to four unique substituents. In the given molecule, the carbons are numbers from left to right. Carbons 1, 3, 5, 6, and 8 are all bound to at least two hydrogen atoms and cannot be stereocenters. import pmx file into blender
