Given below are two statements: Statement I : The boiling points of...
Given below are two statements:
Statement : 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 : The boiling points of aldehydes and ketones are lower than the alcohols of similar molecular masses due to the absence of -bonding.
In the light of the above statements, choose the most appropriate answer from the options given below :
Options
- ABoth Statement and Statement are incorrect.
- BStatement is correct but Statement is incorrect.
- CStatement is incorrect but Statement is correct.
- DBoth Statement and Statement are correct.
Correct answer
D. Both Statement and Statement are correct.
Step-by-step solution
The boiling points of aldehydes and ketones are higher than hydrocarbons of comparable molecular masses. It is due to weak molecular association in aldehydes and ketones arising out of the dipole-dipole interactions. Also, their boiling points are lower than those of alcohols of similar molecular masses due to absence of intermolecular hydrogen bonding.
