Interpretation:
The structure of the product formed as a result of the given reaction is to be proposed based on the given IR spectrum.
Concept introduction:
Absorption of IR radiation causes excitations of vibrational motion of the atoms in a molecule. The vibrational motion can be of different types. In stretching vibrations, the bond length changes periodically. In bending vibrations, the bond angle or dihedral angle changes periodically. This may be an in-plane vibration or out of plane vibration.
The changes in the vibrational motion of the atoms in a molecule are quantized, i.e., the energy of vibrational motion can only have certain discrete values. In general, the frequency of the quantum of radiation absorbed and the frequency of vibration are the same.
The energy needed to excite molecular vibrations depends on the bond strength as a bond can be considered to behave like a spring. In turn, this also means it depends on the mass of the atoms that form the bond. In effect, this means the absorption peaks in the IR spectrum are characteristic of the bond between a particular pair of atoms. They are characteristic of the

Is the correlation good? Would a better fit be obtained by plotting the lattice energies as a function of (1 — d*/d)/d, as theoretically suggested, with d* = 34.5 pm? You must use a standard graphing program to plot the graph. It generates an equation for the line and calculates a correlation coefficient.
