Below is the question I am trying to answer. I think after much debate, I may have it. Does anyone know if I am close to being right?
Does cis and trans isomeric compounds display different properties? Why?
Cis means on the same side and trans means on the opposite side. Cis Isomeric compounds are different from trans isomeric compounds because trans isomers are more stable. This is because the large groups attached to the double bond are further apart.
Someone answered my questions.
I don't know if you have seen my response to your first question; however, I don't think this answers the question although you haven't said anything particularly wrong.
Cis means on the same side and trans means on the opposite side. The atoms are on the same side as the double bond. Cis Isomeric compounds are different from trans isomeric compounds because trans isomers are more stable. Trans isomer are on the opposite sides of the double bond. This is because the large groups attached to the double bond are further apart.
See my last response to your original post.
Your original post is around properties, where as your discussion is around stability. I agree the stability will affect the chemical properties, but also consider physical properties. How will having groups on the same side or opposite sides affect physical properties such as boiling point?
Not all cis are less stable than the trans isomer. Cyclooctene where the carbon chains are cis is more stable than the potential trans version due to ring strain.
