Because , Cis isomer are same group on same side of the c=c bond . & those are bulky group on the same side , they are formed steric repulsion to each other then Cis isomer are less stable than trans isomer is same group of opposite side of c=c bond no formation of steric repulsion to each other. and trans isomer is more stable than Cis isomer.....
Cis-2-butene is less stable than trans-2-butene because of steric hindrance - in the cis form, the two bulky methyl groups are next to each other, causing repulsion and strain in the molecule. This strain is relieved in the trans form where the methyl groups are on opposite sides of the double bond, leading to a more stable conformation.
The trans-benzalacetophenone isomer is the major product in aldol condensation because it is more thermodynamically stable due to the extended conjugation in the molecule, leading to a more favorable resonance stabilization. The trans isomer also experiences less steric hindrance compared to the cis isomer, making it the preferred product.
There are three isomers of dibenzalacetone because of the different possible arrangements of the benzene rings and the carbonyl groups on the central carbon atom. These configurations lead to geometric isomers, where the relative positions of the benzene rings and carbonyl groups differ, resulting in three distinct isomeric forms.
Cis isomers have higher internal energy compared to trans isomers due to the steric hindrance caused by the proximity of bulky substituents in the cis configuration. This leads to increased strain and repulsion between the atoms, resulting in higher internal energy. Trans isomers, on the other hand, have a more stable conformation with less steric hindrance.
Trans decalin and cis decalin are both cyclic hydrocarbons with two fused rings. The main difference lies in the orientation of the rings. In trans decalin, the two rings are on opposite sides of the molecule, while in cis decalin, they are on the same side. This difference in orientation affects the overall shape and stability of the molecules. Trans decalin is more stable and less strained than cis decalin, which can lead to differences in their physical and chemical properties.
The cis-trans isomerism tend to be very stable. Typically, trans isomers are more stable however, an exception lies in cis-trans isomers which makes them more stable than trans isomers.
Trans-polyisoprene is more stable than cis-polyisoprene due to the absence of steric hindrance in the trans configuration, which allows for better alignment of the polymer chains. This results in a more ordered structure and increased stability.
Trans-decalin is more stable than cis-decalin due to reduced steric hindrance in the trans conformation, which allows for a more staggered conformation and less repulsion between the hydrogen atoms. This results in lower energy and greater stability compared to the cis conformation.
Cis-2-butene is less stable than trans-2-butene because of steric hindrance - in the cis form, the two bulky methyl groups are next to each other, causing repulsion and strain in the molecule. This strain is relieved in the trans form where the methyl groups are on opposite sides of the double bond, leading to a more stable conformation.

The trans isomer also experiences less steric hindrance compared to the cis isomer, making it the preferred product.
13-cis lycopene is more stable than 7-cis and 11-cis because it has a more extended conjugated system, making it less prone to isomerization and oxidation. The increased delocalization of electrons in 13-cis lycopene results in higher stability compared to 7-cis and 11-cis isomers.

cis/trans isomerism (also known as geometric isomerism) is a form of stereo isomerism describing the relative orientation of functional groups within a molecule. The terms cis and trans are from Latin, in which cis means "on the same side" and trans means "on the other side" or "across". Usually, for acyclic systems trans isomers are more stable than cis isomers. This is typically due to the increased unfavorable steric interaction of the substituents in the cis isomer. Therefore, trans isomers have a less exothermic heat of combustion, indicating higher thermochemical stability.trans-1,2-dichlorocyclohexanecis-1,2-dichlorocyclohexane

cis. In cis, the electronegativity is concentrated on one side of the isomer, resulting in a net dipole moment, hence it is polar. In trans, the electronegativity is cancelled out by substituent groups on opposite sides of the isomer, there is no net dipole moment, and thus, it is non polar.
The trans community is generally more polarized in terms of societal acceptance and representation compared to the cis community.
