5. Sp 2 Carbon sp 2 carbon has three hybrid orbitals at 120 o angle in one plane (forming sigma bonds with three such carbons) and a hybridized orbital at right angles to the plane.

6. Now each of these sp 2 hybridized carbons combine with each other to form a sheet of hexagonal arranged network.

7. Each C atom contains an unhybridized p orbital. Together due to resonance they form rings of delocalized electrons.

9. 1.42 A o 3.4 A o

10. The delocalised electrons in the unhybridized p orbital are free to move anywhere within the sheet - each electron is no longer fixed to a particular carbon atom. Because of these free electrons graphite is a good conductor of electricity. There is, however, no direct contact between the delocalised electrons in one sheet and those in the neighbouring sheets.
