Hydrogen bonds by Jun
-
a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom.

-
Ethylene glycol (C₂H₄(OH)₂) has two hydroxyls groups. Here hydrogen bonding is present between the two groups due to molecular geometry.

Molecules that have +,- charged regions also dissolve in water
ex) carbohydrates and proteins
: :
=hydrophilic!

Calorie: Amount of heat energy takes to raise 1g of water1 degree celsius
~ It is twice as much energy than other fluids ~

It is because water‘s hydrogen bond becomes rigid when it freezes.
Spreading the molecules out into a lattice decrease density of the ice
and this causes ice to float!
+A body of water freezes from the top and the top insulates the deeper water, keeping it from freezing. This protects aquatic life forms over the winter.
