A question about resonance and hydrogen bonding?
1-In the following molecule (methylene blue), http://pubchem.ncbi.nlm.nih.gov/image/structurefly... which atoms can bear a + charge as a result of resonance? please specify.
2-Given the delocalization of the positive charge due to resonance, which group or atom that can best engage in hydrogen bonding with the partially acidic Al-OH and Si-OH groups on the surfaces of alumina and silica particles, respectively, which prevail in neutral or mildly acidic media like ethanol (EtOH).
I appreciate a good answer :)

1) both the NMe2 and the thiolether groups
2) the nitrogen forming part of the six-member ring because its lone pair doesn't engage in the resonance structures.
