  Graphite cannot be classified as.......... (a) conducting solid         (b) network solid (c) covalent solid              (d) ionic solid

Answer:

                  (d) Graphite can't be classified as ionic solid as graphite is not made up of ions. It is made up of carbon atoms covalently bonded to three carbon atoms so, it is a covalent solid. Since, the formation of covalent bond occurs throughout the crystal therefore, it is a type of network solid. Due to presence of free electron graphite is also classified as conductor solid.
