Question

The hybrid states of carbon in diamond, graphite and acetylene are respectively

Solution

Correct option is

 

Carbon in diamond is arranged in a tetrahedral structure

                                                                 sp3 hybridised carbon. 

In graphite it is arranged in trigonal planner geometry

                                                                 sp2 hybridised carbon

In acetylene (CH ≡ CH) the geometry is linear 

                                                                 sp hybridised carbon.
