The boiling points of aldehydes and ketones lie in between alkanes and – InterviewSolution

1.	The boiling points of aldehydes and ketones lie in between alkanes and alcohols of comparable masses because :
Answer» Alkanes are polar Aldehydes and KETONES are non-polar alkanes are nonpolar and aldehydes and KETONE contain polar gtC=O group and lower alcohols have H-bonding. Alkanes are held TOGETHER by weak Vander Waals forces (being non - polar) , aldehydes and ketones contain polar. gtC=O group and held together by STRONG dipole-dipole attraction and lower alcohol have H-bonding, which is stronger than dipole dipole attraction. Answer :D
