vancomycin is an especially useful antibiotic for treating infections in cancer patients on chemotherapy and renal patients on dialysis. which oh groups are bonded to sp2 hybridized carbon atoms? select all that apply.

In vancomycin, the only OH group(s) bonded to an sp²‑hybridized carbon are those that are phenolic (on the aromatic ring), because aromatic ring carbons are sp² hybridized.

All other OH groups in vancomycin (for example, those on sugar-like side chains) are attached to sp³ carbons and therefore do not meet the condition in the question.
