The percentage of p-character of the hybrid orbitals in graphite and diamond are respectively.

Options

A. 33 and 25
B. 50 and 75
C. 67 and 75
D. 33 and 75

Answer

C

Explanation

In diamond , each carbon is `sp^3` hybridised while in graphite each carbon has `sp^2` hybridisation .
In `sp^(3)` , p- character `to (3)/(4) xx 100 = 75%`
In `sp^(2)` , p-character `to (2)/(3) xx 100 = 66.6 - 67%`
