The hybrid orbitals with \( 33.33 \% \) Scharacter are involved in the bonding of one of the crystalline allotropes of carbon. The allotrope is :

1. carbon black
2. Graphite
3. Diamond
4. Gas carbon

Correct answer: Graphite

Solution

sp2 hybrid orbitals contain one s and two p orbitals, so the s-character is 1/3 = 33.33%. Graphite is made of sp2-hybridized carbon atoms arranged in planar hexagonal sheets.
