Options:
Answer:
Solution:
13. Hex-3-ene : shows G.I. 14. But-2-enoic acid : each C bears two different groups : shows G.I. 15. But-1-ene : terminal CH2 has two H : no. 16. 1,4-Dichlorobut-2-ene : shows G.I. 17. Cyclohexene : the ring is too small for a trans double bond, only one form exists : no. 18. Hepta-2,4-diene : both double bonds stereogenic : shows G.I. 19. 1-Bromo-2-methylcyclohexane : cis-trans forms exist : shows G.I. 20. Methylenecyclohexane : the ring carbon has two identical ring paths and CH2 has two H : no. 21. Acetaldehyde oxime : C=N with different groups on C : shows G.I. (syn-anti). 22. 1,2-Dichloroethene : shows G.I. 23. 2,3-Dimethylbut-2-ene : two CH3 on each carbon : no. 24. But-2-ene-1,4-diol : shows G.I.
Ans. Show G.I. : 13, 14, 16, 18, 19, 21, 22, 24. Do not : 15, 17, 20, 23.
