What are the relative energy levels of the three staggered conformations of 2,3-dimethylbutane when looking down the C2―C3 bond? Conformation: A and B are equal energy, and C is the lowest energy conformation C is the highest energy conformation and A is the lowest (energy level of B is in between the two) A is the highest energy conformation and C is the lowest (energy level of B is in between the two) A and B are equal energy, and C is the highest energy conformation B is the highest energy conformation and C is the lowest (energy level of A is in between the two)
