Options

A. Statement-1 is True, Statement-2 is True , Statement-2 is a correct explanation for Statement-1
B. Statement-1 is True, Statement-2 is True , Statement-2 is not a correct explanation for Statement-1
C. Statement- 1 is True, Statement-2 is False
D. Statement-1 is False, Statement -2 is True

Explanation

To determine the validity of the statements regarding the reactivity of acetylene and ethylene towards electrophilic addition reactions, let's analyze each statement step by step.

### Step 1: Understanding the Structures
- **Acetylene (C2H2)** has a triple bond between the two carbon atoms, which consists of one sigma bond and two pi bonds.
- **Ethylene (C2H4)** has a double bond between the two carbon atoms, consisting of one sigma bond and one pi bond.

### Step 2: Electrophilic Addition Mechanism
- In electrophilic addition reactions, an electrophile (E+) attacks the electron-rich double or triple bond.
- The more electron-rich the bond, the more reactive it is towards electrophiles.

### Step 3: Reactivity Comparison
- Acetylene, with its triple bond (two pi bonds), has a higher electron density compared to ethylene, which has only one pi bond.
- The presence of two pi bonds in acetylene makes it more reactive towards electrophilic addition reactions than ethylene, which has only one pi bond.

### Step 4: Analyzing Statement-1
- **Statement-1:** "Acetylene is more reactive than ethylene towards electrophilic addition reactions."
- This statement is **True** because acetylene has a higher electron density due to the presence of two pi bonds, making it more reactive.

### Step 5: Analyzing Statement-2
- **Statement-2:** "Acetylene contains two pi bonds."
- This statement is also **True** as acetylene indeed has two pi bonds in its triple bond structure.

### Conclusion
Both statements are true:
- Statement-1 is true because acetylene is more reactive than ethylene towards electrophilic addition reactions.
- Statement-2 is true because acetylene contains two pi bonds.

### Final Answer
- Statement-1: True
- Statement-2: True
