Given below are two statements:
In the light of the above statements, choose the most appropriate answer from the options given below:
| Statement I | The boiling points of aldehydes and ketones are higher than hydrocarbons of comparable molecular masses because of weak molecular association in aldehydes and ketones due to dipole-dipole interactions. |
| Statement II | The boiling points of aldehydes and ketones are lower than the alcohols of similar molecular masses due to the absence of H-bonding. |
| 1. | Statement I is incorrect but Statement II is correct. |
| 2. | Both Statement I and Statement II are correct. |
| 3. | Both Statement I and Statement II are incorrect. |
| 4. | Statement I is correct but Statement II is incorrect. |
