Concept explainers
(a)
Interpretation:
The fish-hook curved-arrow notation to derive the missing resonance structure is to be stated.
Concept introduction:
Resonance is the phenomena of the delocalization of pi electrons to give extra stability to the molecule. This extra stability comes from the distribution of the energy of the molecule in the resonance structures formed.
(b)
Interpretation:
The fishhook mechanism for the co-
Concept introduction:
The co-
(c)
Interpretation:
The reason behind the fact that diene part of the polymer has mostly trans double bond stereochemistry is to be stated.
Concept introduction:
The co-polymer is the polymer obtained by the polymerization of two or more different monomer units. The copolymers are usually formed by the condensation polymerization. Some examples of copolymers are nylon and polyethylene.

- A. B. b. Now consider the two bicyclic molecules A. and B. Note that A. is a dianion and B. is a neutral molecule. One of these molecules is a highly reactive compound first characterized in frozen noble gas matrices, that self-reacts rapidly at temperatures above liquid nitrogen temperature. The other compound was isolated at room temperature in the early 1960s, and is a stable ligand used in organometallic chemistry.
