1. The bond length between two double-bonded nitrogen atoms within a molecule of a certain compound is less than that between two single-bonded carbon atoms within another molecule. Given that N and C are next to each other in the periodic table, how would you expect the bond dissociation energies and bond strengths of these two bonds to compare?
2. A molecule of ethene (C2H4) contains a double bond between the two carbon atoms. A molecule of ethyne (C2H2) contains a triple bond between the two carbon atoms. How would you expect the lengths, strengths, and dissociation energies of these two bonds to compare?
