Question

2. What is the relationship between these two structures? OH and OH a) Identical structures b) Enantiomers c) Diasteriomers d) Constitutional Isomers 3. Which newman projects represents the least stable conformation of butane? CH, CH3 HC H Н.С СH, CH3 CH2 H Н Н Н Н H CH3 Н D C В A

Answer 1

ng Ans 2) = C.). Diastereomers, becarise both structures have opposite configuration and non-mirror images of each other one MU on the s' configuration - R configuration & These are not identreal isomers because o both have different configuration 2). These are not enantiomers because 'these are not superimposable mimar images these are not constitutional isomers because of so here same bonding pattern 3) A is least stable conformation of butane because it has higher energy b oots O H 4 H cinta .
