What molecules can have cis and trans isomers?

Answer 1

In the realm of organic chemistry, both rings and olefins support such geometric isomerism.

#2-"butene"# can clearly support #"cis/trans"# isomerism, as can any other internal olefin with greater chain length.

Any ring structure that is disubstituted can also support #"cis-trans"#, #"3-membered"# to #"six-membered"# rings support this isomerism most clearly.

It would be helpful to represent these systems on paper (which needs to be practiced as well), so I implore you to construct real models of these systems using the standard model kits.

Molecules with double bonds, such as alkenes and some cyclic compounds, can have cis and trans isomers.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
