Discuss the hybridisation of carbon atoms in allene `(C_(3)H_(4))` and show the `pi`-orbital overlap.

Explanation

To discuss the hybridization of carbon atoms in allene (C₃H₄) and to show the π-orbital overlap, we will follow these steps:

### Step 1: Understand the Structure of Allene
Allene has the molecular formula C₃H₄. Its structure can be represented as:
```
H H
\ /
C
