Question

In allene ($C_3{H}_4$), the type(s) of hybridisation of the carbon atoms is(are):

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

Answer 1

Answer: (B)

$sp$ and $s{p}^2$

Allene is $H_{2}C=C=C{H}_2$.

There is one $sp$ carbon atom and two $s{p}^2$ carbon atom.

Hence, the correct option is $\text{B}$
