Q81 · Chemistry
Given below are two statements :
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.
In the light of the above statements, choose the most appropriate answer from the options given below :
- 1Statement I is incorrect but Statement II is correct.
- 2Both Statement I and Statement II are correct.Official answer
- 3Both Statement I and Statement II are incorrect.
