1. Identify the chirality centers in the following molecules. Please draw them, and label the chiral centers b asterik() (a) Cis-1,2-dimethylcyclobutane (c) 2,4-Dimethylheptane (e) Cis- 1,3-dichlorocyclopentane (b) 3,3,5-trimethylheptane (d) Trans-1,4-dibromocyclohexane (t) S-2-butanol 2. Draw a tetrahedral representation of the following compounds, a) R-2-chlorobutane c) S-2-butanol e) R-3-bromo-1-pentene g) (2S,3R)-2,3- dibromopentane b) R-2-pentanol d) Meso form of 1,3- Dimethyl cyclohexane f) Meso form of 2,3-dibromobutane h) HSCH CH(NH:)CO2H 3. Assign R or S configuration to the chirality centers of the following molecules CI CH3 CH3 c) CH2CH Br OH CH,CH OH Cl Br h) Htitin HOCH CH 4. Assign R, S configuration to each chirality center in the folloeing molecules. I dentify which are enantiomers, and which are diastereomers, and which are alike ( identical). CLI
