Concept explainers
(a)
Interpretation: The given compounds are to be arranged in order of increasing reactivity in electrophilic
Concept introduction: The replacement or substitution of one
(b)
Interpretation: An explanation corresponding to the statement that given reaction will not lead to the formation of product is to be stated and the synthesis of A from Benzene and B from phenol is to be predicted.
Concept introduction: The replacement or substitution of one functional group with another different functional group in any chemical reaction is termed as substitution reaction. The electron deficient chemical species that contains positive charge are known as electrophile. In electrophilic aromatic substitution reaction, electrophile takes the position of hydrogen atom by attacking the electron rich carbon atom of benzene.
