Give two examples of: Unsaturated hydrocarbons involving `C-=C` bond

Explanation

To answer the question, "Give two examples of unsaturated hydrocarbons involving C≡C bond," we will follow these steps:

### Step 1: Understand Unsaturated Hydrocarbons
Unsaturated hydrocarbons are organic compounds that contain at least one double bond (C=C) or triple bond (C≡C) between carbon atoms. They are called "unsaturated" because they do not contain the maximum number of hydrogen atoms that can be bonded to the carbon skeleton.

**Hint:** Remember that unsaturated hydrocarbons can have either double or triple bonds.

### Step 2: Identify Hydrocarbons with Triple Bonds
