Question

14. Assertion: Two different atoms or groups of atoms are exchanged in double
displacement reactions.
Reason: A double displacement reaction usually occurs in solution and
one of the products, being insoluble precipitates out.​

Answer 1

Answer:

both A andB is correct and B is the correct explanation of A

Answer 2

Double Displacement Reactions

Explanation:

• Both Assertion and Reason are the correct statements, but the reason is not the correct explanation for the assertion.
• During a double displacement reaction, indeed, two different atoms or groups of atoms are exchanged, but this happens because of the nucleophilic attack.
• Nucleophilic attack of one group onto another group present in the solution that ultimately leads to the release of another to form the different compound.
• Also, generally, it takes place in a solution with one product precipitating out, but it is not the correct explanation of assertion.
