Ans. Diastereomers. Sol. Both are pent-3-en-2-ol. In (a) the double bond has the E arrangement (CH 3 and CH(OH)CH 3 on opposite sides) and C-2 is R; in (b) it has the Z arrangement (the two carbon groups on the same side - the CH 3 bond drawn straight down) and C-2 is S. Same connectivity but the molecules differ in double-bond geometry (and also at C-2); stereoisomers that are not mirror images : diastereomers.
