Interpretation: The mechanism for the given reaction should be explained.
Concept Introduction:
Optically active: Optical active molecule rotates the plane polarized light.
Racemization: it is the process in which the pure enantiomers are converted into a mixture of D and L forms of isomers.
Enantiomers: they are chiral molecules whose mirror images are not superimposable.
Chirality: It refers to a Carbon atom in a molecule that contains four different substituents.
D form: They are enantiomers which rotates plane polarized to clockwise direction.
L form: They are enantiomers which rotates plane polarized to anti-clockwise direction.
R and S nomenclature: it is used to assign the molecule using CIP rules.
The CIP rules are as follows:
Select the chiral carbon and assign the numbers according to the decreasing
If the numbering follows clockwise direction then the molecule is termed as R and if it follows anti-clockwise direction then molecule is termed as S.
Leaving group: it is the fragment that leaves the substrate in a
Nucleophile: donates pair of electrons to positively charged substrate resulting in the formation of

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.
