Interpretation:
The possible isomers formed from the given substituted benzenes has to be determined and the structures for the dibromobenzene and tribromobenene has to be drawn separately.
Concept Introduction:
For monosubstituted benzene:
Monosubstituted benzenes are organic compounds that are derived from the benzene by substituting one of the benzene’s hydrogens with an atom or a group of atoms. The general molecular formula for the monosubstituted benzene is
For disubstituted benzene:
Disubstituted benzenes are replaced by two benzene’s hydrogens with two atoms or groups of atoms. The disubstituted can form three isomers namely, ortho-isomers, meta-isomers and para-isomers. The general molecular formula for the disubstituted benzene is
For trisubstituted benzene:
If two substituent atoms or groups substitute two benzene’s hydrogens in the benzene ring, then the compound is called trisubstituted benzene. The general molecular formula for the trisubstituted benzene is

Using radii from Resource section 1 (p.901) and Born-Lande equation, calculate the lattice energy for PbS, which crystallizes in the NaCl structure. Then, use the Born-Haber cycle to obtain the value of lattice energy for PbS. You will need the following data following data: AH Pb(g) = 196 kJ/mol; AHƒ PbS = −98 kJ/mol; electron affinities for S(g)→S¯(g) is -201 kJ/mol; S¯(g) (g) is 640kJ/mol. Ionization energies for Pb are listed in Resource section 2, p.903. Remember that enthalpies of formation are calculated beginning with the elements in their standard states (S8 for sulfur). The formation of S2, AHF: S2 (g) = 535 kJ/mol. Compare the two values, and explain the difference. (8 points)arrow_forward
