Discussion Overview
The discussion revolves around the capability of a specific molecule to form hydrogen bonds. Participants explore the conditions under which a molecule can act as a hydrogen bond donor or acceptor, focusing on molecular structure and polarity.
Discussion Character
- Exploratory
- Debate/contested
- Conceptual clarification
Main Points Raised
- Some participants propose that the molecule can accept hydrogen bonds from other molecules but cannot act as a hydrogen bond donor due to the absence of hydrogen atoms.
- Others question the ability of double-bonded oxygens to participate in hydrogen bonding, suggesting that there is nothing inherently preventing them from accepting hydrogen bonds.
- A participant explains that hydrogen bonds are distinct from covalent bonds like C=O and that electronegative atoms like oxygen can create dipoles that facilitate hydrogen bonding with polar molecules.
- There is a suggestion that while hydrogen bonding might occur, it may not be strong due to the molecule's overall polarity being relatively low.
Areas of Agreement / Disagreement
Participants express differing views on the ability of the molecule to act as a hydrogen bond donor or acceptor, indicating that multiple competing perspectives remain unresolved.
Contextual Notes
Limitations include assumptions about the molecular structure and the specific interactions involved in hydrogen bonding, as well as the dependence on definitions of polarity and hydrogen bonding criteria.
This is not a homework question.

It could accept hydrogen bonds from other molecules, but given that it doesn't have any hydrogens, it would not be able to act as a hydrogen bond donor.

With the oxygens all double bonded to the carbons where would the hydrogen bond to?

Well, what is needed for an atom in a molecule to act as a hydrogen bond acceptor? (hint: read https://en.wikipedia.org/wiki/Hydrogen_bond)

Hydrogen bonds aren't the same as the bonds between the double bonded C=O. Oxygen and Nitroghen have a very high electronegativity (They love electrons). So in a molecule they are bonded to, they hold most of the negative charge creating poles within the molecule, because if they have the electrons, the other atoms don't leaving them with a positive charge. If another molecule is introduced (say water) that is polar and contains hydrogen, their poles can interact creating an attractive force that's not really a bond but like I said just an attractive force. This interaction is considered hydrogen bonding. So you see it doesn't matter that double bond's exist between the C=O as long as there is dipole attractive forces.
However, in this particular molecule, I don't think the hydrogen bonding would be that strong because it is not all that polar to begin with. But hydrogen bonds could exist because the molecule is slightly polar.
