With respect to graphite and diamond, which of the statement (s) given below is (are) correct? 1 . Graphite has higher electrical conductivity than diamond 2 . Graphite is harder than diamond 3 . Graphite has higher C - C bond order than diamond 4 . Graphite has higher thermal conductivity than diamond

Step-by-step solution

Here 1, 3 and 4 are correct as Graphite has higher electrical and thermal conductivities than diamond. All C- atoms in graphite are s p 2 hybridised so due to partial double bond character in graphite, bond order will be more than 1 but in diamond Bond order is one. Here only statement 2 is incorrect as diamond is more hard than graphite.
