    okay so what is the order of who has the highest and lowest among function groups...

    i have (increasing boiling points'0:

    alkanes

    aldehydes/ketones

    alcohols

    carboxylic acids



    where do amines go? aldehyde or ketones are higher?

    thanks!

    i thought alcohols have the highest bp cuz they got the strongest h-bonds... :confused:

    Carboxylic Acids are able to dimerize? IE form two Hydrogen bonds between the carbonyl oxygen and the alcohol group. They have the highest BP because of that...

    alkanes

    aldehydes/ketones

    amines

    alcohols

    amides (I think..)

    carboxylic acids


    Primary and secondory amines contain N-H bonds, so they are able to H-bond with each other. However, the N-H bond is not as polar as the O-H bond seen in alcohols and carboxylic acids, so their boilings points are generally lower.
