Bonding and structure

Allotropes of carbon

Graphene

single layer of hexagons

Delocalised electrons that can move within its structure

Graphite

Layers and each carbon is bonded to 3 others

Diamond

Carbon is bonded to 4 other carbons

Tethrahedral structure

Has no delocalised electrons

Describe how London forces form between halogen moelcules

• uneven distribution of electrons

• Results in a instaneous dipole

• Induces second dipole

Electronegativity

• Atom’s relative ability to attract a bonding pair of electrons in a covalent bond
