The correct Answer is:
To analyze the statements provided in the question, we will evaluate each statement one by one and determine whether they are true or false. ### Step 1: Evaluate Statement 1 **Statement 1:** Amines are less basic than alcohols. - **Explanation:** Amines contain a nitrogen atom with a lone pair of electrons, which can easily donate to protons (H⁺), making them Lewis bases. In contrast, alcohols contain an oxygen atom, which also has a lone pair but is more electronegative than nitrogen. This high electronegativity causes the oxygen to hold onto its electrons more tightly, making it less likely to donate the lone pair. Therefore, amines are generally more basic than alcohols. - **Conclusion:** Statement 1 is **False**. ### Step 2: Evaluate Statement 2 **Statement 2:** Secondary amines give carbylamine reactions. - **Explanation:** The carbylamine reaction is a specific reaction that occurs with primary amines, not secondary amines. In this reaction, a primary amine reacts with chloroform (CHCl₃) and a strong base (like KOH) to produce an isocyanide (carbylamine). Secondary amines do not participate in this reaction. - **Conclusion:** Statement 2 is **False**. ### Step 3: Evaluate Statement 3 **Statement 3:** In Hofmann-bromide reaction, amide is converted to amines with the same number of carbon atoms. - **Explanation:** The Hofmann bromamide reaction involves the conversion of an amide into a primary amine. During this reaction, one carbon atom is lost in the process. The amide (R-C(=O)-NH₂) is treated with halogen (X₂) and a base, resulting in the formation of an amine (R-NH₂) and the loss of one carbon atom. Thus, the final product has one less carbon atom than the original amide. - **Conclusion:** Statement 3 is **False**. ### Final Conclusion After evaluating all three statements: - Statement 1: False - Statement 2: False - Statement 3: False The correct option is **B: False, False, False**. ---
