Cis vs trans

Postby haleyervin7 » Thu Nov 29, 2018 10:27 pm

When we are told to draw a Lewis structure that could either be cis or trans, and we are asked to determine if it is polar, doesn’t this depend on how we drew the molecule? Is there a convention that favors cis or trans when drawing Lewis structures that would help us determine if a molecule is polar or not?

Yes, polarity does depend on whether the molecule is cis or trans.
I don't believe we will ever be given a molecule that could be either and asked about it's polarity if it's not specifically told which way it should be drawn.

In that case, I would think that whether the molecule is cis or trans will be given

Hi where can we find the topic of cis and trans?

Yes, polarity depends on shape in general, and whether a molecule is cis or trans changes its shape. Cis and trans is not a key topic in this class, but if you wish to learn more about it, try using the index of your textbook to find pages where it is mentioned :)
