Red blood cells have no nucleus, making more room to carry oxygen-binding haemoglobin.
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 hydrogen bonding.Choose the most appropriate answer from the options given below:
Both Statement I and Statement II are correct.
Both Statement I and Statement II are incorrect.
Statement I is correct, but Statement II is incorrect.
Statement I is incorrect, but Statement II is correct.
To solve this problem, we need to analyze the boiling points of aldehydes, ketones, hydrocarbons, and alcohols.Statement I: Aldehydes and ketones have higher boiling points than hydrocarbons of comparable molecular masses.• This is due to the presence of dipole-dipole interactions in aldehydes and ketones.• Hydrocarbons, being non-polar, only have weak van der Waals forces.• Therefore, Statement I is correct.Statement II: Aldehydes and ketones have lower boiling points than alcohols of similar molecular masses.
