Question

Key concepts: molecular represenations, stereolsomers, RS enantiomeric excess, IPAC naming covention Provide the IUPAC name for each of the following molecules 0% HJC BM How similar are the names for B and C, even though there is the single change to the structure 2 Rank the priorities of these functional groups and substituents using Cahn-Ingold-Prelog nomenclature. Highest priority will be 1 and lowest will be 5; show your rationale CH:CH:CH CH CHCH:CH CHs,-SCH,-CH: CH:CH:CHCH CHCH, -CH2NHOH,-CH:NO Draw dash/wedge representations for all of the isomers of chloroisopropylcyclohexane including stereoisomers. Clearly indicate which structures are related as configurational isomers. Designate appropriate configurational isomers to be cis or trans. Draw each structure in its most stable chair conformer 4. Using the template below, draw the appropriate dashes and wedges to create a representation of (2S,3R,4S)-3-amino-4-bromo-4-chloro-3-methyl-2-hydroxypentanoic acid. OH Now, draw a Fischer projection of the molecule placing the carboxylic acid at the top of the projection. * How many planes oOmmetry does each of the following molecules possess? 5. Br Br

Answer 1

Answer for (3) wedge form , check R and S comfiguration for all chiral carbons given

in this molecule . We simply need to place atoms in order of their priority(atomic number)

and in doing so if we move clockwise direction then our configuration is R an dif we move counterclockwise then our configuration is S . Also our least priority group must below plane.
Wedge form, check R and S configuration for all choral carbons given in this molecule . We simply need to place atoms in order of their priority(atomic number) and in doing so if we move clockwise direction then our configuration is R and if we move counterclockwise then our configuration is S . Also our least priority group must below plane
