(a) How many asymmetric centers does the following compound have?
(b) How many stereocenters does it have?
Options:
Answer:
C
Solution:
The compound is 4-chlorohex-2-ene, CH3-CH=CH-CHCl-CH2-CH3.
(a) Asymmetric (chirality) centres: only C4, which is attached to four different groups (H, Cl, CH2CH3 and CH=CHCH3) - 1.
(b) Stereocentres include asymmetric centres plus the sp2 carbons whose group interchange interconverts stereoisomers: C2 and C3 of the double bond each carry two different groups (E/Z isomerism exists), so stereocentres = 1 + 2 = 3.
Ans. (C) (a) 1, (b) 3.
