Question

State True or False.

In dilute benzene solutions, equimolar addition of $R_{3}N$ and $HCl$ produce a substance with a dipole moment. In the same solvent, equimolar addition of $R_{3}N$ and $S{O}_3$ produce a substance having an almost identical dipole moment.

• A. True
• B. False

Answer 1

The correct option is A True

In dilute benzene solutions, equimolar addition of $R_{3}N$ and $HCl$ produce a substance with a dipole moment. In the same solvent, equimolar addition of $R_{3}N$ and $S{O}_3$ produce a substance having an almost identical dipole moment.

This is because both $HCl$ and $S{O}_3$ are Lewis acids and can react with the amine base to form polar substances which undergo ionic dissociation in a solvent sufficiently more polar than benzene.
