Question “Several alkene compounds are given below. Indicate if each compound can exist as stereoisomers. CH_3 CH…”
Answer
This concept is used to determine whether an alkene compound can exist in stereoisomers.
Stereoisomers are isomers with the same molecular formula, but differ in the arrangement of the atoms.
Stereoisomers can exist for Alkenes about double bonds.
Cis/trans are stereoisomers. E/Z are stereoisomers.
If two identical groups are located on the same side of the double bond it is cis isomer.
If two identical groups are located on opposite sides of the double bonds, it is trans isomer.
If two groups with high priority are located on the same side of the double bond it will be Z isomer.
If the double bond is broken by two groups of high priority, it will be E isomer.
a.
The following alkene can be found:
It is possible to exist as transstereoisomers.
b.
The following alkene can be found:
It is possible to exist as E/Zstereoisomers.
c.
The following alkene can be found:
It can’t exist as stereoisomers.
d.
The following alkene can be found:
It is possible to exist as stereoisomers.
Ans: Part A
The given alkene is possible to exist as stereoisomers.
Part b
The given alkene is possible to exist as stereoisomers.
Part c
The given alkene is not possible to exist as stereoisomers.
Part d
The given alkene is possible to exist as stereoisomers.
Conclusion
Above is the solution for “Several alkene compounds are given below. Indicate if each compound can exist as stereoisomers. CH_3 CH…“. We hope that you find a good answer and gain the knowledge about this topic of science.
