In allene $\left(\mathrm{C}_{3} \mathrm{H}_{4}\right)$, the type(s) of hybridisation of the carbon atoms is (are):
  1. $s p$ and $s p^{3}$
  2. $s p$ and $s p^{2}$
  3. only $s p^{2}$
  4. $s p^{2}$ and $s p^{3}$

Solution

Allene $\left(\mathbf{C}_{3} \mathbf{H}_{4}\right)$ is $\stackrel{s p^{2}}{\mathrm{H}_{2}} \mathrm{C}=\stackrel{s p}{\mathrm{C}}=\stackrel{s p^{2}}{\mathrm{CH}_{2}}$
