Concept explainers
(a)
Interpretation:
The structure of compound X with the molecular formula
Concept introduction:
The cis – trans (E/Z) isomer can be predicted with respect to the double bond. The isomers can be predicted with respect to the substituents present in carbon – carbon double bond. If the substituents are present on the same side, it is called cis (or) Z isomer. If the substituents are present on opposite sides, it is called Trans (or) E isomer.
Example:
The stereoisomerism is the arrangement of atoms in molecules whose connectivity remains the same but their arrangement in different in each isomer.
The two molecules are described as stereoisomers if they are made of the same atoms connected in the same sequence, but the atoms are positions differently in space.
Chiral centre: A chiral centre is defined as the tetrahedral carbon atom in an organic molecule that is connected to four non-identical groups/substituents. It is sometimes known as a stereo genic centre.
The carbon atom bonded to four unlike groups is called an asymmetric carbon atom and is also known as chiral carbon.

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
