The potential energy of two atoms as a function of internuclear distance is shown in the diagram below. Identify the longer bond and the stronger bond.

The ball-and-stick molecular model of methyl yellow, an azo dye used for plastics, is shown below:

Complete the structure by identifying the positions of the multiple bonds present in methyl yellow.

The following figure below shows the structure of ethane and ethene. Would it be easier to rotate the central C–C bond in ethane or ethene?

The Lewis structure below shows the carbonate ion with its C–O bond lengths. All of the C–O bonds in the carbonate ion are equal in length and a little longer than the usual 123 pm for a C–O double bond. Does this mean that the C–O double bonds in the carbonate ion are weaker than the usual C–O double bonds?

The following figure shows the Lewis structure of eugenol, an aromatic component of clove oil. Determine the total number of σ and π bonds in the eugenol molecule?

A bond-forming orbital overlap is shown in the following figure. Which of the following bonds could be formed? A) Cl—Cl σ, B) C—O π, C) C—C π, or D) C—Cl σ?

List the following molecules in from longest to shortest bond between carbons: H₂NCCNH₂, H₂NCH₂CH₂NH₂, H₂NCHCHNH₂.
