(a)
Interpretation:
Anticipating the isolation of the potentially aromatic hydrocarbon B, a group of chemists irradiated compound A with ultraviolet light. Compound C was obtained as a product instead of B.
The reason for compound B might be expected to be unstable in spite of its cyclic array of 4n+2 π electrons is to be stated.
Concept introduction:
The stability of
(b)
Interpretation:
The formation of compound B is allowed by the pericyclic selection rules is to be explained.
Concept introduction:
Pericyclic reactions deal with electrons shift in a concerted manner. Moreover, in these reactions the breaking of reactant bonds and the formation of product bonds are formed at the same time.i.e., without the formation of intermediates. The word ‘pericyclic’ means around the cycle. Notably, the pericyclic reactions are classified as electrocyclic, cycloaddition and sigmatropic reactions based on the activation of reaction, the number of electrons involved and the stereochemistry outcome of the reactions. The selection rules of pericyclic reaction deal mostly on the
(c)
Interpretation:
The formation of the observed product C is to be explained.
Concept introduction:
Pericyclic reactions deal with electrons shift in a concerted manner. Moreover, in these reactions the breaking of reactant bonds and the formation of product bonds are formed at the same time.i.e., without the formation of intermediates. The selection rules of pericyclic reaction deal mostly on the rates of reaction and does not tell anything about position of equilibrium and equilibrium constant values.
