6) Explain how o and a bonds are similar and how they are different.
A) Differences: o bonds are stronger and result from end- to -end overlap and all single bonds are o bonds; a
bonds between the same two atoms are weaker because they result from side-by-side overlap, and
multiple bonds contain one or more bonds (in addition to a o bond).
B) Similarities: Both types of bonds result from overlap of atomic orbitals on adjacent atoms.
C) Both A and B are correct
6) Explain how o and a bonds are similar and how they are different.
A) Differences: o bonds are stronger and result from end-to-end overlap and all single bonds are o bonds; a
bonds between the same two atoms are weaker because they result from side-by-side overlap, and
multiple bonds contain one or more n bonds (in addition to a o bond).
B) Similarities: Both types of bonds result from overlap of atomic orbitals on adjacent atoms.
C) Both A and B are correct
7) How many o and a bonds are present in the molecule HCN (H-C=N) ?
A) two o (H-C and C-N) and two A
B) two o (H-C and C-N) and one
C) one o (H-C) and three n
Nitrogen is capable of forming single, double, or triple bonds, and the figure that follows shows the potential energy as a function of internuclear distance for each of these types of bonds. Match the three curves in the figure (A, B and C) to the three types of bonds. Explain your reasoning.
