If one hydrogen in a hydrocarbon is replaced by a halogen
a. n-pentane
b. 2-methylbutane
c. 2,4-dimethylpentane
d. methylcyclobutane
(a)
Interpretation: The number of isomers that can be obtained when one hydrogen atom in each of the given compound is replaced by a chlorine atom.
Concept introduction: Structural isomerism occurs when two compounds have same number of atoms but the spatial arrangement of the atoms is different from each other. If one hydrogen atom of a hydrocarbon is replaced by a halogen atom, the number of isomers that exists for the substituted compound depends on the number of types of hydrogen in the original hydrocarbon.
To determine: The number of isomers that can be obtained when one hydrogen in n-pentane is replaced by a chlorine atom.
Answer to Problem 45E
Answer
Three isomers are obtained when one hydrogen atom of n-pentane is replaced by a chlorine atom.
Explanation of Solution
Explanation
The isomer is
The given compound n-pentane has five carbon atoms in the longest carbon chain. When hydrogen of first carbon of n-pentane is replaced by chlorine atom, then the isomer named
Figure 1
The isomer is
The given compound n-pentane has five carbon atoms in the longest carbon chain. When hydrogen of second carbon of n-pentane is replaced by chlorine atom, then the isomer named
Figure 2
The parent chain contains five carbon atom and chlorine group is attached to second carbon.

Answer to Problem 45E
Answer
Three isomers are obtained when one hydrogen of methylcyclobutane is replaced by a chlorine atom.
Explanation of Solution
Explanation
The isomer is
In the given compound methylcyclobutane, the ring of four carbon atoms is considered as the parent chain. Methyl group is attached at first carbon. When hydrogen of the methyl group is replaced by chlorine atom, then the isomer named
