Concept explainers
(a)
Interpretation:
The name of the given molecule should be determined.
Concept Introduction:
The general formula of ketone and aldehyde is:
Where, R is an alkyl group. In case of ketone, R group can be same on both sides or can be different.
Now, the naming of aldehyde and ketone is given as:
- First choose the longest continuous chain of carbon atoms having carbonyl group known as parent chain.
- The numbering of parent chain should be done in a way that the carbonyl group and substituents get the lowest number.
- The root name of the carbon chain is same as in case of
alkanes , but “−e” ending is replaced by “−al” in case of aldehyde and in case of ketone, “−e” ending is replaced by “−one”. - The appropriate name should be given to every alkyl group (substituent) as and denote its position on the parent chain with the number.
- The alkyl groups are written in alphabetical order.
(b)
Interpretation:
The name of the given molecule should be determined.
Concept Introduction:
Aldehyde and ketone both contains carbonyl group. In case of aldehyde, carbonyl group is present at the end of the hydrocarbon chain and in case of ketone, carbonyl group is present between two carbon atoms.
The general formula of ketone and aldehyde is:
Where, R is an alkyl group. In case of ketone, R group can be same on both sides or can be different.
Now, the naming of aldehyde and ketone is given as:

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.
