Yes, the correct answer is option B, which states that ethane has 7 covalent bonds.
Ethane is a simple organic compound with the molecular formula C2H6.
Each carbon atom in ethane forms 4 covalent bonds with the hydrogen atoms that are bonded to it. This means that each carbon atom forms a total of 4 covalent bonds. Since there are two carbon atoms in ethane, the total number of covalent bonds formed by the carbon atoms is 4 * 2 = 8 covalent bonds.
Each hydrogen atom in ethane forms 1 covalent bond with the carbon atom that it is bonded to. This means that each hydrogen atom forms a total of 1 covalent bond. Since there are 6 hydrogen atoms in ethane, the total number of covalent bonds formed by the hydrogen atoms is 1 * 6 = 6 covalent bonds.
Therefore, the total number of covalent bonds in ethane is 8 + 6 = 14 covalent bonds. However, since each covalent bond is a shared pair of electrons, this means that each covalent bond is counted twice. Therefore, the total number of covalent bonds in ethane is 14 / 2 = 7 covalent bonds.
This is the correct answer, and it can be confirmed by looking at the structure of ethane shown above. Each carbon atom forms 4 covalent bonds with the hydrogen atoms that are bonded to it, and each hydrogen atom forms 1 covalent bond with the carbon atom that it is bonded to. This gives a total of 7 covalent bonds
