Intermolecular force: Difference between revisions

Though both not depicted in the diagram, water molecules have four active bonds. The oxygen atom can interact with two hydrogens to form two hydrogen bonds through its two lone pairs, and, of course, the other hydrogen atom can also interact with a neighbouring molecule. Intermolecular hydrogen bonding is responsible for the high boiling point of [[water]] (100&nbsp;°C) compared to the other [[Hydrogen chalcogenide|group 16 hydrides]], which have little capability to hydrogen bond. Intramolecular hydrogen bonding is partly responsible for the [[secondary structure|secondary]], [[tertiary structure|tertiary]], and [[quaternary structure]]s of [[protein]]s and [[nucleic acid]]s. It also plays an important role in the structure of [[polymers]], both synthetic and natural.<ref>{{Citation | vauthors = Lindh U | contribution = Biological functions of the elements | veditors = Selinus O | title = Essentials of Medical Geology | pages = 129–177 | publisher = Springer | place = Dordrecht | year = 2013 | edition = Revised | isbn = 978-94-007-4374-8 | doi = 10.1007/978-94-007-4375-5_7 }}</ref>
