1. | 2. | ||
3. | 4. |
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. |
