Question

18. Provide the correct hexagonal conformation or Ring-flipped chair conformats cyclohexane (as parent chain) compounds. Then circle the more stable chair com ir conformations for the following stable chair conformation Flat Hexagon structure formation A Chair conformation B Chair conformation A Chair confort Chair conformation B ..CH3 - CH₃ 39. The following compounds have 2 stereogenic carbons, therefore 4 stereoisomeric structures (3 if there is meso-form) These are not cyclic compounds. a) Draw the structure. b) Identify the stereogenic carbons. e) Assign the Cahn-Ingold-Prelog order of priority for the elements attached to cach chiral cent d) Draw the all the stereosiomers for your compound. Assign the R and S configuration of each carbon. label the enantiomeric pairs and indicate the diastereomeric relationships, and if forms. 2,4-dihydroxypentanoic acid Pentan-2,4-diol
