Concept explainers
(a)
Interpretation:
The resonance forms of pentadienyl radical to show the three carbon atoms that bear unpaired electron are to be stated.
Concept introduction:
The delocalization of lone pair or free electrons from one place to another is known as resonance. The stability of compound depends upon the number of resonating structures. More the resonating structures of compound more will its stability.
(b)
Interpretation:
The number of molecular orbitals in the molecular orbital picture of pentadienyl radical is to be stated.
Concept introduction:
Molecular orbital diagrams are used for determining the bonding in molecules using linear combination of atomic orbitals. The number of molecular orbitals formed is equal to the number of atomic orbitals that combine with each other.
(c)
Interpretation:
The number of nodes presents in lower-energy molecular orbital and highest-energy molecular orbital of pentadienyl radical is to be predicted.
Concept introduction:
Molecular orbital diagrams are used for determining the bonding in molecules using linear combination of atomic orbitals. The number of molecular orbitals formed is equal to the number of atomic orbitals that combine with each other.
(d)
Interpretation:
The molecular orbitals of pentadienyl system in order of increasing energy are to be drawn.
Concept introduction:
Molecular orbital diagrams are used for determining the bonding in molecules using linear combination of atomic orbitals. The number of molecular orbitals formed is equal to the number of atomic orbitals that combine with each other.
(e)
Interpretation:
The number of electrons present in each molecular orbital of pentadienyl radical is to be stated.
Concept introduction:
Molecular orbital diagrams are used for determining the bonding in molecules using linear combination of atomic orbitals. The number of molecular orbitals formed is equal to the number of atomic orbitals that combine with each other.
(f)
Interpretation:
An explanation to show that molecular orbital picture agrees with the resonance picture that shows the delocalization of unpaired electron on the three carbon atoms is to be stated.
Concept introduction:
Molecular orbital diagrams are used for determining the bonding in molecules using linear combination of atomic orbitals. The number of molecular orbitals formed is equal to the number of atomic orbitals that combine with each other.
(g)
Interpretation:
The carbon atoms that share the positive charge and the picture agree with the resonance structure or not are to be stated.

- These are synthesis questions. You need to show how the starting material can be converted into the product(s) shown. You may use any reactions we have learned. Show all the reagents you need. Show each molecule synthesized along the way and be sure to pay attention to the regiochemistry and stereochemistry preferences for each reaction. If a racemic molecule is made along the way, you need to draw both enantiomers and label the mixture as "racemic". All of the carbon atoms of the products must come from the starting material! ?
