Question
Chapter 12, Problem 48E
Interpretation Introduction
Interpretation:
Whether the semimetals or non-metals are more electronegative is to be stated.
Concept introduction:
Electronegativity is a term which describes the tendency of any species to pull the shared pair of electrons towards itself. More is the electronegativity of an element; more is the attraction of electron pairs towards itself. In a given

Show that a molecule with configuration π4 has a cylindrically symmetric electron distribution. Hint: Let the π orbitals be equal to xf and yf, where f is a function that depends only on the distance from the internuclear axis.
(a) Verify that the lattice energies of the alkali metal iodides are inversely proportional to the distances between the ions in MI (M = alkali metal) by plotting the lattice energies given below against the internuclear distances dMI. 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. (b) From the graph obtained in (a), estimate the lattice energy of silver iodide. (c) Compare the results of (b) with the experimental value of 886 kJ/mol. If they do not agree, explain the deviation.
Can I please get help with #3 & 4? Thanks you so much!
