Cis and Trans

Postby Ashley McClearnen 1B » Mon Nov 26, 2018 5:49 pm

In lecture today, we talked about the difference between cis and trans molecules. I understand the difference, but is it better for a molecule to be cis or trans?

Being cis or trans is really dependent on the biological function of the molecule. Having a cis configuration is convenient for the cisplatin chemotherapy drug mentioned in class, but for a different compound with a trans configuration, it may prove to be more effective for its function.

If a polar bond is needed between molecules, then a cis molecule is preferred (it's polar). If the desire is to prevent polar bonds from forming, then a trans molecule is preferred (it's non-polar).

There are pros and cons to each shape, so it is really just dependent on what the intended purpose is of the molecule.

The cis or trans property of the molecule depends on its polarity. This means cis or trans is more beneficial to a molecule depending on its function.

It just depends.

The cis configuration is polar which means it can create dipole dipole interactions and create a stronger bond compared to the trans configuration

There's no definite answer to which is better. The preferred version depends on the purpose of the molecule. The situation at hand will determine the more desired form between the two.

It depends on what the molecule is being used for, because cis will usually be polar and trans will usually be nonpolar.

It's all situational and depends on the molecule's purpose.

yea it depends on which is more beneficial in terms of polarity. If you want to have a nonpolar molecule with a zero dipole moment then do trans but if you want a polar molecule with a nonzero dipole moment, then cis.
