Concept explainers
(a)
Interpretation:
The classification of the given molecule as achiral or chiral is to be stated.
Concept introduction:
A carbon atom that has four nonequivalent atoms or groups attached to it is known as the chiral carbon atom. Chiral carbon centers are also called as asymmetric or stereogenic centers. A carbon atom that does not have four nonequivalent atoms or groups attached to it is known as an achiral carbon atom.
Answer to Problem 6.1P
The given molecule is a chiral molecule.
Explanation of Solution
The structure of the given compound is shown below as,
Figure 1
Four different groups are attached to the carbon atom that means it is a stereogenic center. The molecule in which stereogenic center is present is known as the chiral molecule. Therefore, the given molecule is a chiral molecule.
The given molecule is a chiral molecule.
(b)
Interpretation:
The classification of the given molecule as achiral or chiral is to be stated.

Answer to Problem 6.1P
The given molecule is an achiral molecule.
Explanation of Solution
The structure of the given compound is shown below as,
Figure 2
Two same groups are attached to the carbon atom that means it is not a stereogenic center. The molecule in which no stereogenic center is present is known as an achiral molecule. Therefore, the given molecule is an achiral molecule.
The given molecule is an achiral molecule.
(c)
