Hydrogen bonding is considered as the strongest IMFA and it is present for molecules with a Hydrogen atom that is chemically or covalently bonded to Nitrogen, Oxygen, and Fluorine atom (electronegative atom). Answer and Explanation: The answer is...
Hydrogen bonding allows animals to cool themselves using perspiration because such a large amount of heat is needed to break hydrogen bonds between water molecules. Hydrogen bonding keeps water in its liquid state over a wider temperature range than for any other comparable-sized molecule. ...
Hydrogen bonding between adjacent polymer chains (intermolecular bonding); Hydrogen bonding between different parts of the same chain (intramolecular bonding; Hydrogen bonding of water molecules to –OH groups on the polymer chain ("bound water") that helps maintain the shape of the polymer. The exa...
in reactions with Al clusters27, have illustrated how partial atomic charges and bonding orbitals28 and the doping of heteroatoms affects such HER processes29,30,31,32,33, and have demonstrated the Eley–Rideal and Langmuir–Hinshelwood mechanisms in the presence of two OH-group molecules34. ...
and hydrogen are closer to the nucleus of the oxygen atom. Hence, the attractive force to pull the shared pairs of electrons towards the nucleus is more. The bond becomes polar, making the water molecule a dipole. This helps in the formation of hydrogen bonding between the water molecules. ...
