Hydrogen bonding

[Sally kim 4F]

What is the significance of hydrogen bonding that Lavelle said in the lecture?

[AVerma_F19]

They are very strong intermolecular forces that give molecules like H2O special properties.

[Jessica Esparza 2H]

They are another form of bonding that isn't covalent or ionic. It deals with partial negatives and positives.

[Sydney Jacobs 1C]

Hydrogen bonds are present in molecules with N, O, or F atoms. An H atom on one molecule is bonded to an electronegative atom, giving it a partial positive charge, and when it becomes close to another electronegative atom that has an available lone pair, a hydrogen bond forms. Hydrogen bonds are not as strong as covalent bonds.

[John Arambulo 1I]

Hydrogen bonding is a special type of dipole-dipole interaction due to the high electronegativity of Nitrogen, Oxygen, and Fluorine, so hydrogen bonds occur in water, ammonia, and hydrogen fluoride. They can only occur when there are lone pairs around those atoms.

[Aayush Patel 3B]

Hydrogen is also very important because it is plays an integral role in maintaining the shape of proteins such as DNA, RNA, cellulose, etc.

Can someone explain how hydrogen bonding affects the polarity of a molecule? I'm trying to understand the connection between these two concepts. Thank you so much!

[Clarice Chui 2C]

Also, Hydrogen bonding helps explain higher melting points.
