Graphite is a good conductor of electricity. Its electrical conductivity is due to the fact that (CPMT 2010)
A.it is an allotrope of carbon.
B.it has C-atoms arranged in large plates of rings of
C.in it C-atoms are sp2 hybridised.✓ Correct
D.it is a non-crystalline substance.
Explanation
Graphite is a good conductor of heat and electricity because in structure of graphite carbon atoms are hybridized, thus it has free electrons present in the arrangement which are free to move. Hence, the correct option is (c).
