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

Question

TestHub · Accepted Answer

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.
