(a)
Interpretation:
The curved arrow mechanism of the formation of compound A is to be stated.
Concept introduction:
(b)
Interpretation:
The three basic steps of electrophilic aromatic substitution in the mechanism are to be stated.
Concept introduction:
An electrophile is a positive species which has an affinity towards negative charge.
The
(c)
Interpretation:
The product obtained if the reaction b followed the usual directing effects of alkyl substituents is to be stated. A reason as to why the celestolide instead of the expected product is formed is to be suggested.
Concept introduction:
The replacement of hydrogen atom attached to a carbon atom of electron-rich benzene ring by an incoming electrophile is known as electrophilic aromatic substitution reaction. The rate of electrophilic aromatic substitution reaction depends on the substituted group on the aromatic ring. The ring deactivating group retards the electrophilic aromatic substitution reaction and ring activating group enhances the electrophilic aromatic substitution reaction.
