The given compounds should be arranged in a specific order for that which property should be considered. We have to discuss it in detail. Also, the given compound rank should be determined so that we have to arrange it in the order starting from the most ionic to least. Concept Introduction: No bond can be 100% ionic. Every ionic bond will have a small amount of covalent character in it. Such covalent character of the compounds which are ionic is described with the help of Fajan's rule. Fajan's rule states that the covalent character of a molecule gets increased by the polarization of the anion by the cation. When a cation exerts a force to distort the anion's electron cloud, it is called the polarizing power.The anion's tendency to get polarized is termed as polarisability. Hence, when there is a greater polarization, there is a more covalent character.

Decide whether these proposed Lewis structures are reasonable. proposed Lewis structure H-H-0 Q: :0: || :C1= C-C1: : Cl- :0: I C =C1: Is the proposed Lewis structure reasonable? Yes. No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* 0 Yes. No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* Yes. No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:* * If two or more atoms of the same element don't satisfy the octet rule, just enter the chemical symbol as many times as necessary. For example, if two oxygen atoms don't satisfy the octet rule, enter "O,0". X

8.83 Construct a Born-Haber cycle for the formation of the hy- pothetical compound NaCl2, where the sodium ion has a 2+ charge (the second ionization energy for sodium is given in Table 7.2). (a) How large would the lattice energy need to be for the formation of NaCl2 to be exothermic? (b) If we were to estimate the lattice energy of NaCl2 to be roughly equal to that of MgCl2 (2326 kJ/mol from Table 8.1), what value would you obtain for the standard enthalpy of formation, AH, of NaCl2?
