Concept explainers
(a)
Interpretation:
The preparation of isotopically labeled deuterium compound is to be stated.
Concept introduction:
The replacement or substitution of one
(b)
Interpretation:
The preparation of isotopically labeled deuterium compound is to be stated.
Concept introduction:
The replacement or substitution of one functional group with another different functional group in any chemical reaction is termed as a substitution reaction. In a nucleophilic substitution reaction, nucleophile takes the position of leaving the group by attacking the electron-deficient carbon atom.
