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.

WebJun 5, 2014 · Explanation: Molecules which are capable of hydrogen bonds have hydrogen atoms which are covalently bonded to highly electronegative elements (O, N, F). The presence of hydrogen bonding between molecules of a substance indicates that the molecules are polar. This means the molecules will be soluble in a polar solvent such as … WebJan 30, 2024 · The increase in boiling point happens because the molecules are getting larger with more electrons, and so van der Waals dispersion forces become greater.

Therefore, other methods must be used to determine the melting points of inorganic ... WebAug 24, 2024 · 4. When a molecule hydrogen bonds, intramolecular bonds tend to be weakened, and such bonds become longer. Hydrogen bonds can also result in distortion of internal bond angles. However, H-bonds are typically weaker than covalent bonds by an order of magnitude or so, so H-bonds will perturb but hardly alter the conformation of rigid … hide a field using jquery
