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...
