Properties of Covalent Compounds.

What is the first statement of the video clip?

• Properties of covalent compounds: when we're looking at the properties of covalent compounds we have to think about the structure of a covalent molecule

• So let's look at a structure here of a water molecule, it's important to remember that this is a discrete molecule

• By discrete I'm saying that there's just one oxygen attached to two hydrogen atoms

• So if we have a look at the bonding involved between the hydrogen and the oxygen its covalent bonding

• And this is the intra molecular bond intra meaning within the molecule

Properties of Covalent Compounds.

What is the Second statement of the video clip?

• if we have a look at the bonding that occurs between the two molecules this is now the inter molecular bond

• So let's look at a structure here of a water molecule, it's important to remember that this is a discrete molecule

• By discrete I'm saying that there's just one oxygen attached to two hydrogen atoms

• So if we have a look at the bonding involved between the hydrogen and the oxygen its covalent bonding

• And this is the intra molecular bond intra meaning within the molecule

Properties of Covalent Compounds.

What is the Third statement of the video clip?

• if we have a look at the bonding that occurs between the two molecules this is now the inter molecular bond

• so the bonding between molecules the intra molecular bonding is strong bonding this is very difficult to break

• By discrete I'm saying that there's just one oxygen attached to two hydrogen atoms

• So if we have a look at the bonding involved between the hydrogen and the oxygen its covalent bonding

• And this is the intra molecular bond intra meaning within the molecule

Properties of Covalent Compounds.

What is the Fourth statement of the video clip?

• if we have a look at the bonding that occurs between the two molecules this is now the inter molecular bond

• so the bonding between molecules the intra molecular bonding is strong bonding this is very difficult to break

• And requires very very high temperatures to break where is the inter molecular bond

• So if we have a look at the bonding involved between the hydrogen and the oxygen its covalent bonding

• And this is the intra molecular bond intra meaning within the molecule

Properties of Covalent Compounds.

What is the Fifth statement of the video clip?

• if we have a look at the bonding that occurs between the two molecules this is now the inter molecular bond

• so the bonding between molecules the intra molecular bonding is strong bonding this is very difficult to break

• And requires very very high temperatures to break. where is the inter molecular bond?

• In this case a hydrogen bond but it could also be a dipole-dipole or a dispersion force

• And this is the intra molecular bond. Intra meaning within the molecule

Properties of Covalent Compounds.

What is the Sixth statement of the video clip?

• if we have a look at the bonding that occurs between the two molecules this is now the inter molecular bond

• so the bonding between molecules the intra molecular bonding is strong bonding this is very difficult to break

• And requires very very high temperatures to break. where is the inter molecular bond?

• In this case a hydrogen bond but it could also be a dipole-dipole or a dispersion force

• These are very weak bonds and these are the ones that break quite easily between these molecules

Properties of Covalent Compounds.

What is the Seventh statement of the video clip?

• And just here's another diagram of water and you'll see here the hydrogen bonds between the hydrogen and the oxygen molecules

• so the bonding between molecules the intra molecular bonding is strong bonding this is very difficult to break

• And requires very very high temperatures to break. where is the inter molecular bond?

• In this case a hydrogen bond but it could also be a dipole-dipole or a dispersion force

• These are very weak bonds and these are the ones that break quite easily between these molecules

Properties of Covalent Compounds.

What is the Eighth statement of the video clip?

• And just here's another diagram of water and you'll see here the hydrogen bonds between the hydrogen and the oxygen molecules

• And it's these that break when you put your hand into a jar of water you do not break the actual covalent bonds within the molecule itself

• And requires very very high temperatures to break. where is the inter molecular bond?

• In this case a hydrogen bond but it could also be a dipole-dipole or a dispersion force

• These are very weak bonds and these are the ones that break quite easily between these molecules

Properties of Covalent Compounds.

What is the Ninth statement of the video clip?

• And just here's another diagram of water and you'll see here the hydrogen bonds between the hydrogen and the oxygen molecules

• And it's these that break when you put your hand into a jar of water you do not break the actual covalent bonds within the molecule itself

• So this gives it some different properties and the first one is a day or they have low melting and boiling points

• In this case a hydrogen bond but it could also be a dipole-dipole or a dispersion force

• These are very weak bonds and these are the ones that break quite easily between these molecules

Properties of Covalent Compounds.

What is the Tenth statement of the video clip?

• And just here's another diagram of water and you'll see here the hydrogen bonds between the hydrogen and the oxygen molecules

• And it's these that break when you put your hand into a jar of water you do not break the actual covalent bonds within the molecule itself

• So this gives it some different properties and the first one is a day or they have low melting and boiling points

• And this is because the weak intermolecular forces are very easy to break

• These are very weak bonds and these are the ones that break quite easily between these molecules
