Question
Chapter 8, Problem 4Q
Interpretation Introduction
Interpretation:
The order from top to bottom for naphthalene, butyric acid, and phenylacetate spots developed on silica gel TLC plate should be determined.
Concept introduction:
TLC works on the principle of separation of constituents of a mixture of compounds based onpolarity. The polar compounds interact with the stationary phase. So, theycan move to smaller distance from the base,whereas, the non-polar compounds tend to move faster as they interact less with the silica gel.Therefore, they move far from the base of the plate.

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).
