Question

Ethane, with the molecular formula $C_2{H}_6$ has:

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

Answer 1

Answer: (B)

The correct option is B $7$ covalent bonds
Ethane with molecular formula $C_2{H}_6$ has seven covalent bonds. $6$ bonds between $C-H$ and one is between $C-C$. The six hydrogen atoms will each share their 1 electron with carbon to form six carbon-hydrogen covalent bonds. The two carbon atoms will each share their 1 electron to form one carbon-carbon covalent bond.
