Because of its polarity and ability to form hydrogen …
WebIn a polar covalent bond containing hydrogen (e.g., an O-H bond in a water molecule), the hydrogen will have a slight positive charge because the bond electrons are pulled more strongly toward the other element. Because of this slight positive charge, the hydrogen will be attracted to any neighboring negative charges. WebThe hydrogen bond length of water varies with temperature and pressure. Although the (mean) H-O···O angle is indicated as 12°, it varies over a wide angle (considering both the quantum nature of the nuclei and thermal fluctuations) with ~50% probability between 4° and 24° at 250 K []. As hydrogen bond strength depends almost linearly on its length …
