Statement-1:Alkanes float on the surface of water
Statement-2: Density of alkanes is in the range of 0.6-0.9 g/ml ,
which is lower than water.

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 analyze the given statements, we will break down the information step by step.

### Step 1: Understanding Statement 1
**Statement 1:** Alkanes float on the surface of water.

To determine if this statement is true, we need to consider the concept of density. Objects that have a lower density than the fluid they are placed in will float, while those with a higher density will sink.

### Step 2: Understanding Statement 2
**Statement 2:** The density of alkanes is in the range of 0.6-0.9 g/ml, which is lower than water.

The density of water is approximately 1 g/ml. Since the density of alkanes (0.6-0.9 g/ml) is indeed lower than that of water, this statement is also true.

### Step 3: Analyzing the Relationship Between the Statements
Since both statements are true, we need to see if Statement 2 provides a correct explanation for Statement 1.

- The density of alkanes being lower than that of water (Statement 2) explains why alkanes float on the surface of water (Statement 1).

### Conclusion
Both statements are true, and Statement 2 is a correct explanation for Statement 1.

### Final Answer
- Statement 1 is true.
- Statement 2 is true.
- Statement 2 is the correct explanation for Statement 1.
