Question

Ethane, with the molecular formula C₂H_6, has

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

Answer 1

The correct option is B

7 covalent bonds.

covalent bond: consists of the mutual sharing of one or more pairs of electrons between two atoms.

Ethane (C₂H₆)

• Ethane is a saturated hydrocarbon in gaseous form.
• Ethane is the second most common alkane, followed by methane. It has two carbon atoms and six hydrogen atoms in it. In a lab environment, sodium propionate is used to produce it.
• Ethane is the most important gaseous fuel. Ethane and heavier hydrocarbons in natural gas can be easily isolated from the gas stream and liquefied under moderate pressure.
• Ethane has six covalent bonds between carbon and hydrogen atoms.
• one covalent bond between Carbon and Carbon atom.

Structure of Ethane

Therefore, the total covalent bond in ethane is 7.

Hence, option (B) is correct.
