Answer:
the answer would be C of not C is B
The correct answer would be the third option. In order for the equilibrium of the reaction to shift to the left, we must decrease the concentration of a reactant or increase the concentration of the product. This is based on Le Chatelier's principle which describes the effect on equilibrium of changes in concentration or pressure of a product or a reactant. Adding more product in a system, would disturbed the equilibrium thus it would cause to reestablish it by shifting the reaction to the left producing the reactants. This would also be the same when you decrease the amount of reactant in the system.
I think 78 hope it’s right
The molecule expand to relieve steric strain before undergoing torsion to a non-planar structure in order to have several resonating structures.
<h3>What is a molecule?</h3>
It should be noted that a molecule simply mean the group of atoms that are bonded together that represents the smallest fundamental unit if the chemical compound.
It should be noted that structures containing fused benzene rings have extensive conjugation. Due to this, they can undergo resonance.
This is vital in decreasing the overall energy of the molecule and helps increase its stability. When there's a change in torsion angle to relieve the steric strain, the molecule won't be planar, hence, the energy will increase and the stability will reduce.
