Concept explainers
a.
Interpretation:
The condensed structural formula of 1, 2-dimethylcyclopropane needs to be drawn.
Concept introduction:
When the carbon atoms of hydrocarbons are arranged in such a way that it results in the formation of ring then it is said to be cycloalkanes (containing single bond only in the ring).
a.

Answer to Problem 57A
Explanation of Solution
The given name is 1, 2-dimethylcyclopropane that means the parent chain contains cyclic ring of 3 carbon atoms and -dimethyl represents the presence of two methyl substituents at position 1 and 2. So, the structure of 1, 2-dimethylcyclopropane is:
b.
Interpretation:
The condensed structural formula of 1, 1-diethyl-2-methylcyclopentane needs to be drawn.
Concept introduction:
When the carbon atoms of hydrocarbons are arranged in such a way that it results in the formation of ring then it is said to be cycloalkanes (containing single bond only in the ring).
b.

Answer to Problem 57A
Explanation of Solution
The given name is 1, 1-diethyl-2-methylcyclopentane that means the parent chain contains cyclic ring of 5 carbon atoms and -diethyl represents the presence of two ethyl substituents at position 1 and one methyl substituent at position 2. So, the structure of 1, 1-diethyl-2-methylcyclopentane is:
