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:
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.
