How do hydrogen bonds affect the boiling point of water?

WebIf you plot the boiling points of the compounds of the Group 4 elements with hydrogen, you find that the boiling points increase as you go down the group. The increase in boiling point happens because the molecules are getting larger with more electrons, and so van der Waals dispersion forces become greater. WebCohesive forces are responsible for surface tension, a phenomenon that results in the tendency of a liquid’s surface to resist rupture when placed under tension or stress.Water molecules at the surface (at the water-air interface) will form hydrogen bonds with their neighbors, just like water molecules deeper within the liquid. d-400 schedule pn north carolina

Understanding How Intermolecular Forces Affect Boiling Points

WebFor a given number of carbon atoms, an unbranched alkane has a higher boiling point than any of its branched-chain isomers. This effect is evident upon comparing the boiling points (bp) of selected C 8 H 18 isomers. An unbranched alkane has a more extended shape, thereby increasing the number of intermolecular attractive forces that must be broken in … WebSep 23, 2024 · Hydrogen bonding can be used to improve the boiling point of a substance in two ways. The first way is by increasing the number of hydrogen bonds between molecules. This can be done by increasing the number of electrons that are shared between molecules. The second way is by increasing the strength of the existing hydrogen bonds.
