Question

Which of the following statements is/are true about amines?

• A. Amine salts are soluble in ether but insoluble in water
• B. Amines have an unshared pair of electrons on nitrogen atom due to which they behave as Lewis acid
• C. Basic character of amines can be understood in terms of their $K_{b}$ and $p K_{b}$ values
• D. All of the above

Answer 1

Answer: (C)

Amines salts are soluble in water but insoluble in organic solvents like ether. Amines have an unshared pair of electrons on nitrogen atom due to which they behave as Lewis base.
Basic character of amines can be explained by their $K_{b}$ and $p K_{b}$ values.
