Can propanone (acetone) Hydrogen bond or does it have just dipole/dipole interactions?

+k for help
 
Thats what I thought, but i can't visualise how it would fit together, in the same way water can,

anyway +k
 
how high is the melting/boiling point? it should give you an indication as to the intermolecular bonding present i think as hydrogen bonding is the strongest of the intermolecular forces
 
56 oc for boiling, I have to compare the forces with propanone and butane (-0.5 oc). They have the same no. of electrons so the same london forces. It just depends on whether they H-bond or just have permanent dipoles
 
You guys are wrong.

Propanone is not an alcohol, meaning there is no OH group creating hydrogen bonds with other molecules. Propanone is different then propanol. It's a ketone, so it has dipole-dipole attractions.
 
I know its a ketone. Surely it doesn't have to be an -OH group for H-bonding to occur? 'I'll trust you anyway..

Thanks for the help +k
 
seriously guys?

noone knew horseshit when i asked for that math optimization.

you cannot be serious.

and i am mad

cool story bro

fuck off

i am mad

jk, its not that bad

well actually it is
 
yeah I hate math. anyway, acetone looks like this

O

ll

H3C-C-CH3

that took some time. but there's no hydrogen bond within acetone, but the carbonyl part can interact with water. thats the C=O part.
 
With resonance there's the potential to hydrogen bond but that would happen so infrequently that effectively No there will not be H bonds formed. This is why acetone evaporates very quickly and makes a good solvent
 
Acetone CANNOT hydrogen bond with other acetone molecules, but it CAN form hydrogen bonds with water or other substances with N, O, or F atom directly bonded to an H atom.
 
Many of the replies in this thread are wrong!



acetone contains an oxygen with two lone pairs and hence can act as a hydrogen bond acceptor. Since it does not contain an electronegtive element (O,F, N) bound to a hydrogen, it cannot act as a hydrogen bond donor. Since it is only capable of being a hydrogen bond acceptor, it would not be capable of hydrogen bonding with itself. However, in solution, it could hydrogen bond with water since water contains a O-H bond.

Soooooooooo, acetone is capable of hydrogen bonding so long as the other party is a hydrogen bond donor.

Hope that helps!
 
Acetone is a ketone, thus it has an oxygen double bonded to the 2nd carbon of the chain. Since hydrogen bonding can only occur with an interaction of an H with N, O, F it is possible to occur. The most likely way that it will happen is if the oxygen gets protinated by an acid, and then a proton transfer reaction would have to occur throughout the compound to get rid of the double bond/ Positively charged oxygen as well as a nucleophilic addition reaction (b/c oxygen will not stably be positive) .....but in short, yea it can form a hydrogen bond, but only if the hydrogen is added from another molecule. Also, if your'e just comparing the strengths of butane and propane, propane will be much stronger because it has a dipole moment between the C and the O (the C being slightly positive, while the O is slightly negative). Hope you find this helpful
 
Yup. Since acetone can only act as a H-bond acceptor it cannot form H-bonds with itself. But it can form Hydrogen bonds with any compound which can act as a h-bond donor.For this reason, the answer to the OP's original question is: yes acetone can form H-bonds
 
i just realized the structure didn't even work lol. or at least I don't think it came out right. at any rate, it's methyl, carbonyl, methyl. i'm sure you know what it looks like.
 
quick chem question as well.plz help
