Concept explainers
(a)
Interpretation:
Out of the two distances between two nitrogen atoms, 50 pm or 75 pm, it is to be determined which one represents higher energy.
Concept introduction:
The energy of the molecule depends on the distance between the two atoms. At a certain distance, called the bond length, the energy reaches a minimum. As the distance between the two atoms increases, the energy of the molecule increases and slowly approaches a constant value as the distance increases to infinity. At distances shorter than the bond length, the energy increases very rapidly.
(b)
Interpretation:
Out of the two distances between two nitrogen atoms, 75 pm or 110 pm, it is to be determined which one represents higher energy.
Concept introduction:
The energy of the molecule depends on the distance between the two atoms. At a certain distance, called the bond length, the energy reaches a minimum. As the distance between the two atoms increases, the energy of the molecule increases and slowly approaches a constant value as the distance increases to infinity. At distances shorter than the bond length, the energy increases very rapidly.
