🌊Giant Covalent Structures

💎

Diamond structure

tetrahedral lattice

diamond how many covalent bonds

4 C-C

diamond M/BP?

very high → strong covalent bonds require high energy to break

Diamond conduct electricity?

No → no charged particles that can move

Graphite structure

layered structure

graphite covalent bond structure?

3 C-C Covalent Bonds

Graphite M/BP?!

high → lots of covalent bonds

can graphite conduct electricity?

yes → delocalised electrons that can move between layers

Why does graphite break easily?

weak intermolecular forces between the layers

Buckminsterfullerene structure?

epcot

Is Buckminsterfullerine a giant covalent bond?!

its simple covalent but its super big (C60)

Buckminsterfullerene M/BP?

low due to simple covalent

Does buckminsterfullerene conduct electricity?

nope → delocalized electrons but CANNOT travel

Buckminster fullerene allotrope structure?

3 C-C Covalent Bonds

Silicon Dioxide what is it?

s a n d

silicon dioxide structure?

tetrahedral (same as diamond)

Silicon Dioxide is a carbon allotrope??

nope
