- Label the following pairs as A) distereoisomers, B) enantiomers, C) conformers, or D) the same. b1 c1 d1 e1 a2 b2 c2 The structures above are labeled a1, a2, b1, b2 ...etc. Using these labels, indicate which compounds above would have an optical rotation ofarrow_forwardStereoisomers share the same connectivity and differ only in the way their atoms are arranged in space. Draw the structure of a compound that is a stereoisomer ofarrow_forwardOn the left is a stereorepresentation of glucose (we discuss the structure and chemistry of glucose in Chapter 25). (a) Convert the stereorepresentation on the left to a planar hexagon representation. (b) Convert the stereorepresentation on the left to a chair conformation. Which substituent groups in the chair conformation are equatorial? Which are axial?arrow_forward
- Locate the stereogenic centers in attached molecule. Compounds may have one or more stereogenic centers.arrow_forwardWhich of the following is the correct definition for a pair of enantiomers? 1) A pair of stereoisomers that are not superimposable mirror images of each other. 2) A pair of stereoisomers that are superimposable mirror images of each other. 3) A pair of stereoisomers that have a plane of symmetry. 4) A pair of stereoisomers that are not mirror images of each other.arrow_forwardIndicate whether the pair of structures shown represent stereoisomers, constitutional isomers, different conformations of the same compound, or the same conformation of a compound view from a different perspective. Note that cis, trans isomers are an example of stereoisomers. Br H3C- Br Br OCH3 H3C Br OCH3 stereoisomers constitutional isomers different conformations same conformation.arrow_forward
