Question

The molecular formula of ethane is \( C_2H_6 \). It has:

• A. 9 covalent bonds
• B. 8 covalent bonds
• C. 7 covalent bonds
• D. 6 covalent bonds

Hint:

Ethane (\( C_2H_6 \)) has 7 covalent bonds: 6 \text{C–H} bonds and 1 \text{C–C} bond.

Answer 1

The Correct Option is C

Step 1: Understanding the structure of ethane. Ethane (\text{C}_2\text{H}_6) consists of: - A single covalent bond (\text{C–C}) between two carbon atoms. - Each carbon forms single covalent bonds with three hydrogen atoms. Total number of covalent bonds: \[ \text{6 (C–H bonds) + 1 (C–C bond) = 7 covalent bonds} \]
Step 2: Explanation of incorrect options.
- 9, 8, or 6 covalent bonds are incorrect as ethane has exactly 7 covalent bonds.
