Question

The hybridisation of $C$ in diamond, graphite and ethyne is in the order :

• A. $s{p}^3,sp,s{p}^2$
• B. $s{p}^3,s{p}^2,sp$
• C. $sp,s{p}^2,s{p}^3$
• D. $s{p}^2,s{p}^3,sp$

Answer 1

Answer: (B)

$s{p}^3,s{p}^2,sp$

In diamond $C$ has $s{p}^3$ hybridisation

In graphite $C$ has $s{p}^2$ hybridisation

In ethyne $C$ has $sp$ hybridisation
