Answer 1

  The answer is (b) 7 covalent bonds

Answer 2

Answer: Option (b) is the correct answer.

Explanation:

A covalent bond is defined as a bond which is formed by sharing of electrons between two or more atoms.

For example, valency of carbon is 4 and in order to attain stability it combines with other atoms and forms covalent bonds.

In $C_{2}H_{6}$ each carbon atom is attached to three hydrogen atoms and both the carbon atoms are attached to each other also.

Hence, it results in the formation of total 7 covalent bonds.
