Both s-cis and s-trans conformers of 1,3-butadiene have a continuous conjugated π system, which of the following statements is true about the s-cis conformer?

The s-cis conformer is lower in energy than the s-trans conformer
The s-cis conformer is higher in energy than the s-trans conformer.
The s-cis conformer has equal energy as the s-trans conformer.
None of these.

second option (B)

Explanation:

The s-cis conformer is higher in energy than the s-trans conformer. The most stable conformer has bent-inward geometry which favors the π bond interaction with methyl/methylene hydrogen/carbon atom hence more crowding with consequent higher energy, this is also responsible for the higher boiling point of the s-cis conformer.

b. is the answer hoped i        

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
