cis-trans
« on: November 18, 2004, 02:48:04 PM »
How do I determine cis-trans from a line structure? I have an example attached. I know cis means having the same groups on the same side, and trans is same groups on opposite sides, but I'm having trouble determing this with line structures.

That would be trans. A cis conformation would have the two alkyl groups on the same side.
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.

Which alkyl groups are you talking about?

the ones attached to the double bond. How many thins are attached to the double bond? There are 2 hydrogens and 2 alkyl groups. The hydrogens are trans to each other and so are te alkyl groups.
