Chemistry Question on p -Block Elements
Graphite is a soft solid lubricant extremely difficult to melt. The reason for this anomalous behaviour is that graphite -
A
has molecules of variable molecular masses like polymers
B
has carbon atoms arranged in large plates of rings of strongly bound carbon atoms with weak interplate bonds.
C
is a non-crystalline substance.
D
is an allotropic form of carbon.
Answer
has carbon atoms arranged in large plates of rings of strongly bound carbon atoms with weak interplate bonds.
