Question

The hybrid orbitals with 33.33% S-character are involved in the bonding of one of the crystalline allotropes of carbon. The allotrope is :

• A. Carbon black
• B. Graphite
• C. Diamond
• D. Gas carbon

Answer 1

The correct option is B Graphite

$s{p}^2$ hybridisation involves mixing of 1 s-orbital and 2 p-orbital. Thus, s orbital contributes one third or 33% of its character to each hybrid orbital. Graphite has $s{p}^2$ hybridisation.
