(b)The constitution of 1-phenyl-1-butene is C6H5CH?CHCH2CH3. The Estereoisomer isThe two higher ranked substituents, phenyl and ethyl, are on opposite sides of the double bond.(c)The constitution of 2-phenyl-2-butene is . The Zstereoisomer is The two higher ranked substituents, phenyl and methyl, are on the same side of the double bond.(d)1-Phenylethanol is chiral and has the constitution . Among the substituentsattached to the stereogenic center, the order of decreasing precedence isHO.C6H5.CH3.HIn the Renantiomer the three highest ranked substituents must appear in a clockwise sense inproceeding from higher ranked to next lower ranked when the lowest ranked substituent is di-
