6. What is the relationship between these two structures? NH2 H- CH3 H- NH, CHE HC- H2N- NH2 CHz a) Identical structures b) Enantiomers c) Diastereomers d) Constitutional isomers
Problem 7.7 Determine the configuration of each of the following as Zor E as appropriate: LOH Y OH (a) (b) (c) (d) Sample Solution (a) One of the doubly bonded carbons bears a methyl group and a hydrogen. According to the Cahn-Ingold-Prelog sequence rules, methyl outranks hydrogen. The other carbon atom of the double bond bears a methyl and a —CH OH group. The-CH2OH group is of higher priority than methyl. Higher (C) — Hzc CH2OH - Higher C(O,H,H) Lower...

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...
19-26 thanks! 19-29* PART 3: 2,3-BUTANEDIOL CH-CH(OH)-CH(OH)-CH, mirror images, not superimposable Build as many models of 2,3-butanediol as you can. First, attach two carbons with a single bond. To each carbon add one carbon, one hydrogen, and one oxygen. To complete the structure, Ti the remaining hydrogen atoms. Remember, a model is not different if it is completely superimposable on one already constructed! 13. How many stereochemically different models are possible for 2,3-butanediol? 14. What characteristic does one of these...
