Question

What are the types of hybridization in $C_3{H}_4$?

Answer 1

$C_3{H}_4$ is allene

$H_{2}C=C=C{H}_2$

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

In $C_3{H}_4$, the central carbon has $sp$ hybridization with $2\sigma$ and $2\pi$ bonds.

The terminal carbons both have $s{p}^2$ hybridization with $2\sigma$ and $1\pi$ bonds.
