Allotropes Of Carbon Flashcards
(14 cards)
What is catenation
When atoms bond to neighbouring atoms in a particular structure
What is diamond commonly used for
-Drill bits in oil exploration and slicing concrete
Jewellery
Why is diamond used for things like drills and jewellery?
Due to its TETRAHEDRAL structure diamond is one of the hardest known materials
What is diamonds sublimation point?
4027 degrees
What is graphite used for?
Pencil leads and nuclear reactor cores to stop or slow nuclear reactions
Why is graphite used for pencil leads?
It’s later like structure makes it soft and flaky so it leaves marks on paper
Why is graphite used to slow nuclear reactions
So much energy is needed to break graphite covalent bonds so it’s tough enough to be used in a nuclear reactor and it’s a good conductor of electricity due to its soup of spare electrons
What is graphites sublimation point?
3600 degrees
What is Buckminsterfullerene’s spherical structure?
60 carbon atoms arranged as 10 hexagons and 12 pentagons which forms the shape of a football (C60 is sometimes called a Bucky ball)
What is a tetrahedral structure?
When each carbon atom is bonded to 4 other carbon atoms by covalent bonds to form a giant crystal lattice
Why does graphene have a sea of delocalised electrons?
Due to its structure being layered hexagons (hexagonal lattice) with each carbon atom bonding to only 3 other atoms it leaves intermolecular space between the layers where electrons are
What is the description of graphene?
Thinnest, lightest, strongest and most stretchy material ever created
What is graphene used for?
Solar panels, smart windows, electronic displays all due to its flexibility and excellent electricity conduction
What could many fullerenes like C60 be used for?
Potentially Drug delivery because the intermolecular forces are weak and melting point is low and can conduct electricity.
