Stilbenes may exist as the trans and cis stereoisomeric forms, but naturally they overwhelmingly occur as the trans isomers due to their higher thermodynamical stability compared to the cis isomers [9].Feb 16, 2021

Is cis stilbene and trans stilbene more stable?
Trans stilbene is an organic compound having two phenyl groups attached to the two carbon atoms of a double bond where the groups are oriented in opposite directions. … It has the two bulky phenyl groups far from each other, making this compound more stable than cis isomers due to less steric hindrance.
Which stilbene is more stable?
Therefore, generally speaking, the trans (E) isomers are more stable and lower in energy than the cis (Z) isomers.
Are trans or cis more stable?
The cis isomer is more stable than the trans isomer by approximately 40 kJ mole− 1. With an increasing number of CH₂ groups to span the two carbon atoms of the double bond, the strain of the trans isomer becomes less severe. For example, the isomeric cyclododecenes are of comparable stability.
Which is more stable out of cis and trans isomers?
Trans isomers are more stable as in trans isomers same group or atom on two different carbon atoms are located on the opposite sides of the carbon-carbon double bond and hence the trans molecule is non-polar. The polarity on both the sides cancels out. So, trans-isomer stability is more than cis.
Does it matter if you use cis or trans stilbene as a starting material?
Does it matter if you use cis or trans stilbene as a starting material? Would this give you the same product? No, it does not matter. The cis and trans-stilbene will give the same alkyne final product.

Why is cis more stable?
In Cis isomer, the groups are present side by side. This gives rise to steric hindrance between the two groups making it less stable.. Whereas in trans isomer, the groups are present on opposite sides, so steric hindrance is minimised in this making it more stable.. This is basic reason.
