Covalent Compounds and Their Properties

The video tutorial explains covalent compounds, which are formed by nonmetals bonding together. It provides examples like CO2 and NCl3, and distinguishes covalent compounds from ionic ones, such as NaCl. The role of hydrogen as a nonmetal in covalent compounds is highlighted, with examples like CH4 and H2O. The video also clarifies that covalent compounds are also known as molecular compounds and touches on organic compounds, which are covalent due to their composition of nonmetals like carbon and hydrogen.

What is a covalent compound?
