Cis isomers are less symmetrical compared to trans isomers, hence they are loosely packed leading to relatively lower melting point. Generally they have higher solubility in inert solvents. So we can differentiate cis and trans isomers on the basis of their boiling point, melt...
To determine this, I drew the 5 isomers of hexane and tried to look for positions to put a double bond for each of them. You get 10 structures of which 4 have cis/trans-isomers.btw.: it's a lot easier if you draw your molecules as "chains" without H-atoms (is there a name ...
The exercise says "It is possible to say that gossyplure (this substance) has two cis double bonds. Assign true or false." I have no idea how to solve this. The answer is "false. The first (left to right) double bond is cis, but the last (left to right) is trans." How can I...
Determine the number and types of isomers that would be possible for triamminetrichlorochromium(III). How many isomers exist of the complex having a formula MA3B3? Draw and name them. How many different alkenes (including cis/trans isomers) can be hydrogenated to form hexane?...

Cahn, Ingold,andPrelogdeveloped a system that, regardless of the direction we are looking at the molecule, will always give the same name (unlike the wedge and dash notation). And that is why this is also known as theabsolute Configurationor most commonly referred to astheRandSsystem. ...
How could you use 1H NMR to distinguish between the given pair of isomers below? Which of the following characteristics does the below-mentioned molecule have? a) Both Chiral carbons are R. b) The molecule is cis. c) Both chiral carbons are S. d)...
When Diels and Alder originally discovered this phenomenon, they assigned the name “endo” to the major product (where the dienophile is pointing “in”, towards the alkene) , and the term “exo” (outside, such as in “exoskeleton”) to refer to the minor product (where...
Trans-violaxanthin is further modified into neoxanthin by NSY—encoded by NDX1—or into cis-violaxanthin by an enzyme still uncharacterized in tomato. Both intermediates are substrates for NCED—encoded by NOT—to be converted into xanthonin. Xanthonin moves across the plastid membrane to the ...
