1. The problem statement, all variables and given/known data CH3CH=CHCH3 What's the cis and trans structure name for this formula? 2. Relevant equations 3. The attempt at a solution I've drew the ciis and trans structure H\ /H C = C / \ CH3 CH3 this is the cis the tran is similar to the cis except the H and CH3 is at the top, CH3 and H is at the bottom of the double bonded C. I'm not sure what's the name of it. i know theres four carbon, so butane is usually what we say it is, but it has a double bond so its butene. So is it cis-butene and trans-butene? I'm not really sure. please help..thank you in advance.
