Answer:
Posible dimers structures: B) and D) (Figure 1)
Explanation:
The correct <u>dimer structures</u> are the ones that have a right <u>intermolecular bonding</u> interacction. In this case we will have hydrogen bonding. This type of interaction is due to the negative polarization in the oxygen and the positive polarization in the hydrogen. (Figure 2)
So, a correct dimer structure is posible if we have an interaction from the negative part (oxygen) to the positive part (hydrogen). The only structures that have this type of interactions are B and D.
