Coupling reaction is an example of
- A nucleophilic addition reaction.
- B nucleophilic substitution reaction.
- C electrophilic substitution reaction.
- D electrophilic addition reaction.
Answer & Solution
Correct Answer
(C) electrophilic substitution reaction.
Step-by-step Solution
Detailed explanation
Coupling reactions, such as the formation of azo dyes from diazonium salts and aromatic compounds (like phenols or amines), involve the attack of a diazonium cation on an electron-rich aromatic ring. The diazonium cation, \(Ar-N_{2}^{+}\), acts as a weak electrophile. It attacks…

Choose the correct answer from the options given below.
Assertion (A): The molality of KCl solution at 25°C is 5 m. (Given molar mass of KCl is 74.5 g/mol). When the solution is cooled to -10°C, the molality of the solution remains unchanged.
Reason (R): The molality of the solution does not change with temperature as the mass remains unaffected with temperature.COMEDK 2025 Medium - Identify the Alkane (molecular formula \(\mathrm{C}_8 \mathrm{H}_{18}\) ) which yields only a single monochloride on Chlorination in the presence of sunlight.COMEDK 2025 Medium
