Cyclobutadiene (1) can be hydrogenated to give cyclobutane (2). Similarly, cyclobutene (3) can also be hydrogenated to give cyclobutane. Which statement is accurate? I was told to ignore differences in angle strain between 1 and 3 for the purposes of this comparison.

a. the magnitude of ΔHH for cyclobutadiene = 2 × the magnitude of ΔHH for cyclobutene.

b. the magnitude of ΔHH for cyclobutadiene > 2 × the magnitude of ΔHH for cyclobutene.

c. the magnitude of ΔHH for cyclobutadiene < 2 × the magnitude of ΔHH for cyclobutene.
