Question

The molecular formula of ethane is C$_2$H$_6$. It has:

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

Hint:

In alkanes like ethane (C$_2$H$_6$), each carbon follows the tetravalency rule, forming four single covalent bonds.

Answer 1

The Correct Option is B

Ethane (C$_2$H$_6$) consists of two carbon (C) atoms forming a single covalent bond (C-C) and six hydrogen (H) atoms bonded to carbon atoms via single covalent bonds (C-H). Since each carbon forms four bonds, the total number of covalent bonds in ethane is 8.
