Ethane, with the molecular formula C H has-

Correct option is C

The correct answer is (c) 7 covalent bonds.
Ethane (C₂H₆) is composed of two carbon atoms and six hydrogen atoms. The structure includes:
· 1 covalent bond between the two carbon atoms (C-C bond).
· Each carbon atom forms 3 covalent bonds with hydrogen atoms (C-H bonds), for a total of 6 C-H bonds.
In total:
· 1 C-C bond.
· 6 C-H bonds.
Therefore, ethane has 7 covalent bonds in total.
Information Booster:
· Covalent bonds occur when atoms share electron pairs.
· In ethane, all bonds are single covalent bonds (also known as sigma (σ) bonds).
· The molecule is part of the alkane group, which consists of hydrocarbons with only single bonds.
