Identify the molecular weight of the compound `'X'` containing carbon and hydrogen atoms only with `3sigma` and `2pi` bonds in one molecule.

Explanation

To determine the molecular weight of compound 'X' containing only carbon and hydrogen atoms with 3 sigma bonds and 2 pi bonds, we can follow these steps:

### Step 1: Understand the Bonding Requirements
- The compound must have a total of 3 sigma (σ) bonds and 2 pi (π) bonds.
- In organic compounds, sigma bonds are typically formed by single bonds, while pi bonds are formed in double or triple bonds.

### Step 2: Identify Possible Structures
- A common structure that fits the requirement of having 3 sigma bonds and 2 pi bonds is acetylene (C₂H₂).
