Concept explainers
(a)
Interpretation:
The Lewis structure of propylene glycol is to be determined by using the following arrangement.
Concept Introduction:
Lewis structure is used for the representation of the bonding between atoms of molecule and lone pair of electrons that present in the molecule.
(b)
Interpretation:
The polar bonds present in the molecule needs to be determined.
Concept Introduction:
The polar bond is also called a covalent bond which is formed between the two unlike atoms having electronegative difference ranges from 0.5-1.9. The polar bond represents the arrow towards the high electronegative element, while the tail towards the low electronegative element. The negative sign is given to the high electronegative element, while the positive sign is given to the low electronegative element.
(c)
Interpretation:
The molecular shape around carbon atom and oxygen atom needs to be determined.
Concept Introduction:
The molecular shape of the compound is including the general shape of the compound or atom, the bond length of the molecule and the bond angles.

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
