Identify the labeled chirality centers as R or S in the molecule shown below. A 2 S , 6 S B 2 S , 6 R C 2 R , 6 S D 2 R , 6 R dentify the labeled chirality centers as R or S in the molecule shown below. Which of the following compounds would be optically active? Which of the following is true of any ( S ) – enantiomer? A It rotates plane-polarized light to the right B It rotates plane-polarized light to the left C It is the mirror image would be the ( R ) enantiomer D It has the highest priority group on the right Which of the following is an alcohol that can exhibit optical activity? Which of the following compounds represents ( S )-2-bromobutane? Identify the chirality centers as ( R ) or ( S ) in the Fischer projection of 2,3-dichlorobutanal given below. Solution Hi please be familiar with priority groups or atoms according to IUPAC nomenclature as well as CIP notation as this is vast info, cannot be discussed here. 1. Answer: 2R,6S (Chiral carbon is attached to carbons, but one carbon has 3 Cl atoms connected & get 1st priority) 2. Answer: 1S,2S 3. Answer: 2) only, remaining two has plane of symmetery. 4. Answer: C) It is the mirror image would be the ( R ) enantiomer ( R & S configuration is differ from dextro (d) and leavo (l) rotatory concept. 5. Answer: 3) only, remaining all are achiral compounds. 6. Answer: 3) only, in fischer projection method in-plane left side group or atom represents below the plane & right-side group or atom represents above the plane. 7. Answer: 1R, 2S (same explanation as above). Hope this helped you! Thank You So Much! Please Rate this answer as you wish.(\"Thumbs Up\") .

2. Solution
Hi please be familiar with priority groups or atoms according to IUPAC nomenclature as well as
CIP notation as this is vast info, cannot be discussed here.
1. Answer: 2R,6S (Chiral carbon is attached to carbons, but one carbon has 3 Cl atoms
connected & get 1st priority)
2. Answer: 1S,2S
3. Answer: 2) only, remaining two has plane of symmetery.
4. Answer: C) It is the mirror image would be the ( R ) enantiomer ( R & S configuration is
differ from dextro (d) and leavo (l) rotatory concept.
5. Answer: 3) only, remaining all are achiral compounds.
6. Answer: 3) only, in fischer projection method in-plane left side group or atom represents
below the plane & right-side group or atom represents above the plane.
7. Answer: 1R, 2S (same explanation as above).
