2.2 Intramolecular Force and Potential Energy
AdvancedMCQGraphicalConceptual25.7k
A grayscale 2D line graph with the horizontal axis labeled 'Internuclear Distance (pm)' and the vertical axis labeled 'Potential Energy (kJ/mol)'. A horizontal dashed reference line is drawn at zero potential energy. Three asymmetric U-shaped potential energy curves are plotted: Curve 1 is drawn as a solid line, Curve 2 as a dashed line, and Curve 3 as a dotted line. Curve 1 has its minimum at the smallest internuclear distance (furthest to the left) and the most negative potential energy (deepest well). Curve 2 has its minimum at an intermediate internuclear distance and intermediate depth. Curve 3 has its minimum at the greatest internuclear distance (furthest to the right) and the least negative potential energy (shallowest well). At very small internuclear distances, all three curves rise steeply above zero potential energy. As internuclear distance increases to the right, all curves asymptotically approach the horizontal zero reference line from below. No other particles, labels, text, or annotations appear.
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?
