Potential energy versus internuclear distance for three carbon-carbon bonds.
Potential energy versus internuclear distance for three carbon-carbon bonds.
The graph below shows the potential energy as a function of internuclear distance for three different carbon-carbon covalent bonds: a single bond (\(\text{C}-\text{C}\)), a double bond (\(\text{C}=\text{C}\)), and a triple bond (\(\text{C}\equiv\text{C}\)).

Which curve corresponds to the \(\text{C}\equiv\text{C}\) bond, and which statement best justifies this assignment?
