(c)
Interpretation:
It is to be identified whether the given molecule is chiral.
Concept introduction:
The molecule with at least one chiral center having no plane of symmetry is called a chiral molecule. A chiral center is a tetrahedral stereocenter. The atom at the chiral center must be
Answer to Problem 5.38P
The given molecule is a chiral molecule.
Explanation of Solution
The structure of the given molecule is
The molecule consists of a ring made up of five carbon atoms and one nitrogen atom. The nitrogen atom is bonded to three different groups having pyramidal shape and a non-bonded electron pair pointing to the unoccupied tetrahedral corner. This makes the nitrogen a chiral center.
As this molecule has only one chiral center, it cannot possess any symmetry, and hence, this is a chiral molecule.
The given molecule is identified as chiral on the basis of the presence of a chiral center.
(d)
Interpretation:
It is to be identified whether the given molecule is chiral.
Concept introduction:

Answer to Problem 5.38P
The given molecule is not a chiral molecule.
Explanation of Solution
The structure of the given molecule is
A chiral center must be an
Therefore, these carbon atoms are also not chiral centers. Hence this is not a chiral center.
The given molecule is identified as achiral on the basis of the presence of a chiral center.
(e)
Interpretation:
It is to be identified whether the given molecule is chiral.
Concept introduction:
The molecule with at least one chiral center having no plane of symmetry is called a chiral molecule. A chiral center is a tetrahedral stereocenter. The atom at the chiral center must be
Answer to Problem 5.38P
The given molecule is not a chiral molecule.
Explanation of Solution
The structure of the given molecule is
The given molecule possesses two chiral carbons. One carbon is bonded to four different groups,
As the bonded atoms are not exactly same, the molecule does not have a symmetry plane; hence, it is a chiral molecule.
The given molecule is identified as chiral on the basis of the presence of a chiral center.
(f)
Interpretation:
It is to be identified whether the given molecule is chiral.
Concept introduction:
The molecule with at least one chiral center having no plane of symmetry is called a chiral molecule. A chiral center is a tetrahedral stereocenter. The atom at the chiral center must be
Answer to Problem 5.38P
The given molecule is not a chiral molecule.
Explanation of Solution
The structure of the given molecule is
The given molecule possesses an inversion center indicated by the blue dot, which reflects all the atoms into identical atoms through
As the molecule has an inversion center, it is not a chiral molecule.
The given molecule is identified as achiral on the basis of the presence of a chiral center.
