Q. 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

Solution:

Here 1, 3 and 4 are correct as Graphite has higher electrical and thermal conductivities than diamond.

All C- atoms in graphite are $\text{s}\text{p}^{2}$ 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.
