B. 7
C. 6
D. 4

Answer

To determine the number of covalent bonds present in ethylene (C2H4), we can follow these steps:

### Step 1: Understand the structure of ethylene
Ethylene is an organic compound with the molecular formula C2H4. It consists of two carbon atoms and four hydrogen atoms.

**Hint:** Remember that ethylene is a simple alkene with a double bond between the carbon atoms.

### Step 2: Draw the Lewis structure of ethylene
In the Lewis structure of ethylene, each carbon atom is bonded to two hydrogen atoms and to each other with a double bond. The structure can be represented as follows:

```
H H
\ /
C=C
/ \
H H
```

**Hint:** The double bond between the carbon atoms indicates that they share two pairs of electrons.

### Step 3: Count the covalent bonds
1. **C-C bond:** There is 1 double bond between the two carbon atoms, which counts as 2 covalent bonds.
2. **C-H bonds:** Each carbon atom is bonded to 2 hydrogen atoms. Since there are 2 carbon atoms, this results in a total of 4 C-H bonds.

Now, we can summarize the total number of covalent bonds:
- 2 (from the C=C double bond)
- 4 (from the 4 C-H single bonds)

### Step 4: Calculate the total number of covalent bonds
Adding these together gives us:
- Total covalent bonds = 2 (C=C) + 4 (C-H) = 6 covalent bonds.

### Final Answer
The number of covalent bonds present in ethylene is **6**.
