The statement that "the electronegativity of N on the Pauling scale is 3.0 in all the nitrogen compounds" is incorrect because:
| 1. | Electronegativity of an element is a variable property. |
| 2. | Pauling scale is not used to measure electronegativity. |
| 3. | The electronegativity of N on the Pauling scale is 12.0 |
| 4. | None of the above. |
