Concept explainers
(a)
Interpretation:
To identify the given compound as primary, secondary or tertiary alkyl halide and give a common name to the given compound.
Concept introduction:
Alkyl halide refers to those organic compounds that consist of halogen atom as a functional group attached to the alkyl chain. The general formula is
In primary alkyl halide, the halogen group is attached to a carbon atom that is connected to two hydrogen atoms and the other carbon atom.
In secondary alkyl halide, the halogen group is attached to a carbon atom that is connected to two carbon atoms and one hydrogen atom.
In tertiary alkyl halide, the halogen group is attached to a carbon atom that is connected to three carbon atoms.

Answer to Problem 8.1P
The common name of the given compound is cyclopentyl bromide. It is a secondary alkyl halide.
Explanation of Solution
The given compound is shown below.
Figure 1
It contains a ring of five carbon atoms. Bromine is attached to the second carbon atom. Therefore, the common name of this compound is cyclopentyl bromide.
The bromine atom is attached to a carbon atom that is connected to two carbon atoms and one hydrogen atom. Therefore, it is a secondary alkyl halide.
The common name of the given compound is cyclopentyl bromide. It is a secondary alkyl halide.

Answer to Problem 8.1P
The common name of the given compound is neopentyl chloride. It is a primary alkyl halide.
Explanation of Solution
The given compound is shown below.
Figure 2
It contains five carbon atoms. Chlorine is attached to the first carbon atom and three methyl groups are attached to the second carbon atom. Therefore, the prefix –neo is used before the name of an alkyl halide. Therefore, the common name of this compound is neopentyl chloride.
The chloride atom is attached to a carbon atom that is connected to two hydrogen atoms and the other carbon atom. Therefore, it is a primary alkyl halide.
The common name of the given compound is neopentyl chloride. It is a primary alkyl halide.
