Q. No.| Statement I | Grignard reagent (R–MgX) reacts with CO₂ followed by acidification to form a carboxylic acid (R–COOH). This on heating with NH₃ forms an amide (R–CONH₂), which on treatment with NaOCl gives a primary amine (R–NH₂). The amine on reaction with CHCl₃/NaOH forms an isocyanide (R-NC). |
| Statement II | Isocyanide (R-NC) on hydrolysis gives Carboxylic acid (RCOOH). |
Choose the correct option:
| 1. | Statement-I and Statement-II both are correct |
| 2. | Statement-I is incorrect Statement-II is correct |
| 3. | Statement-I is correct Statement-II is incorrect |
| 4. | Statement-I and Statement-II both incorrect |
