1.Describe/Explain how Hydrogen bonding occurs between water molecules
-Water is a polar molecule and forms extremely weak interactions/bonds. However, throusands of them are enough to satbilise the large polemerised structure
· Hydrogen bonds are a type of bond that hold individual monomer water molecule together in order to form polymers
· Hydrogen Bonds are formed when OS- part of water molecule is more electronegative than Hs+ part of another h20 mol since the electrons are not shared perfectly equally
· The OS- pole of a molecule pulls the HS+ pole of the molecule because the OS- wants to pull the electrons towards itself from the HS+ region of another water molecule, leaving the hydrogen slightly +ve/O -ve
· This forms weak bonds/interactions called Hydrogen bonds
·
2.Describe/Explain the properties of water
1. Hydrogen bonds in Liquid water and ice have a high Boiling point
-Pure water forms Hydrogen bonds with each other, allowing the polymerized molecule to exists as they do
-Hydrogen bonds forms a network that allow the molecules to slide over each other as the new bonds break/make
-This makes it more difficult for water molecules to break its interactions in the network, difficult to change state form a liquid and a gas, thus water has a high boiling point
Low temperatre
-Water has reduced kinetic energy, so water molecules collide less
-More Hydrogen bonds are formed and Less hydrogen bonds are broken (need…
