Final answer:
In ethane (C₂H₆), each carbon atom is bonded to one other carbon atom and three hydrogen atoms, making a total of four bonds per carbon atom.
Step-by-step explanation:
In ethane, C₂H₆, each carbon atom is bonded to another carbon atom and to three hydrogen atoms to fulfill the requirement of making four covalent bonds.
This molecular structure ensures that each carbon atom in ethane has a total of four bonds, adhering to carbon's tetravalency.
The two carbon atoms are connected by a single sigma bond formed by the overlap of two sp³ hybrid orbitals, while the remaining sp³ hybrid orbitals on each carbon overlap with s orbitals of hydrogen atoms to form carbon-hydrogen sigma bonds.
Due to this bonding arrangement, the molecule of ethane consists of two CH₃ groups that are capable of rotating around the carbon-carbon single bond.
In ethane, each carbon atom is bonded to another carbon and six hydrogen atoms. The molecular formula of ethane is C₂H₆, which means it consists of two carbon atoms and six hydrogen atoms.
The carbon atoms are bonded together by a single bond, and each carbon atom is also bonded to three hydrogen atoms. This results in a total of six hydrogen atoms in the molecule.
