Covalent Bonds and Molecular Compounds

The video tutorial explores whether C2H6 is ionic or covalent. By examining the periodic table, it is determined that both carbon and hydrogen are nonmetals, indicating a covalent bond. The structure of C2H6 is explained, highlighting the sharing of electrons between carbon and hydrogen due to their similar electronegativities. This sharing forms single bonds, confirming C2H6 as a covalent compound. The tutorial concludes with a summary of these findings.

What type of elements are carbon and hydrogen in the periodic table?

• Metalloids
