Concept explainers
(a)
Interpretation:
Given Lewis structure is to be drawn using condensed formula.
Concept introduction:
The condensed formula indicates how the atoms should be connected in a given molecule. To arrive at a total charge of zero, each carbon should have a maximum of four bonds while each oxygen should have a maximum of two bonds and two lone pairs. A parenthesis in the condensed formula represents that the repetitive unit is attached to the previous carbon atom. The CO2 notation denotes a carbon atom that is doubly bonded to one oxygen atom and singly bonded to another. Rings are generally now shown in their condensed formulas, but they are commonly shown in their partially condensed form.

Answer to Problem 1.61P
The condensed formula for the first Lewis structure is: CH3(CH2)2CH3
Explanation of Solution
The given Lewis structure is:
In the given Lewis structure, there are two CH2 units in the middle. In this case, the similar units are shown by using the notation (CH2)n, where ‘n’ is the number of CH2 units. Thus, the condensed formula for this is written as: CH3(CH2)2CH3

Answer to Problem 1.61P
The condensed structure for the given Lewis structure is: (CH3)2CCHCH3
Explanation of Solution
The given Lewis structure is:
In the structure above, there are two CH3 groups attached directly to one of the doubly bonded carbon atom. Thus, a parenthesis has to be used to represent the two CH3 groups attached to one of the doubly bonded carbon atoms. The other doubly bonded carbon atom has one CH3 group attached to it. Thus, the condensed formula for the given Lewis structure is: (CH3)2CCHCH3
