What is the hybrid state of carbon in ethyne, graphite and diamond ?A. `sp^(2), sp, sp^(3)`B. `sp, sp^(2), sp^(3)`C. `sp^(3) , sp^(2) , sp`D. `sp^(2), sp^(3), sp`

Answer» Correct Answer - B
In ethyne, ` H - C -= C - H`, C is sp hybridised .
In graphite , one C atom is attached to 3 other C atoms which are `sp^(2)` hybridised.
In diamond , one C atom is attached to 4 other C atoms which are `sp^(3)` hybridised .
