Which one of the following statements is not correct?
general-sciencechemistry
- AGraphite is a non-metal
- BGraphite is an allotrope of carbon
- CGraphite is a conductor of electricity
- DGraphite has a tetrahedral structure
Explanation
Graphite has a hexagonal layered structure with delocalised electrons, which makes it a conductor of electricity; the tetrahedral structure belongs to diamond, not graphite. Graphite is indeed a non-metal and an allotrope of carbon. Hence statement (D) is the one that is not correct.
