Which one of these is not allotrope
Fullerenes
Diamond
Graphite
Hydrophilic acid
properties of fullerences
Hard due to string covalent bonds between carbon atoms
Does not conduct electricity, because electrons are not free to move and carry electric current
insoluble in water and organic solvents,conducts electricity
All of the above
Name the 3 types of allotrope that we have studied
(a)
one use of fullerences
Their unusual electrical properties mean that they can be used as semiconductors in electric circuits
Cutting tools
Use as a jewelry
Define allotrope
Which one has a 3-D hexagonal structure
Diamond
Fullerences
Graphite
They are made from carbon atoms joined together to make balles or tubes of carbon.
Graphite
Diamond
Fullerence
is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure.
Diamond
Graphite
Sulfur
Hydrophilic acid
Whic one is the properties of diamond and fullerence
Hard due to string covalent bonds between carbon atoms
Does not conduct electricity, because electrons are not free to move and carry electric current
brittle solid that is pale yellow in colour, a poor conductor of electricity, and insoluble in water.
They are typically charge-polarized and capable of hydrogen bonding.
Uses of diamond
As a jewelry
Cutting tools
Insoluble in water
