If the two are on opposite sides, it’s trans. It’s that simple. An easy way to remember this convention is to look at the third letter of the word, for CI S the S stands for S ame and for TR A NS the A stands for A lternate. For example, let’s look at 1,2-dichlorocyclohexane.

WebSteric Arrangement in Cis and Trans Configuration. Polymers with double bonds in the repeat unit give rise to different geometric isomers. For example, 1,3-butadiene can be polymerized to give poly (1,2-butadiene) or either of two geometric isomers of poly (1,4-butadiene). (2) These two isomers are called cis and trans poly (1,4-butadiene). WebCis vs Trans Conformations - Organic Chemistry Video Clutch Prep. Ch. 4 - Alkanes and Cycloalkanes Worksheet See all chapters.
