Covalent Bonding in SO2

The video explores whether sulfur dioxide (SO2) is ionic or covalent. It begins by examining the periodic table, identifying sulfur and oxygen as non-metals, which typically form covalent bonds. The Lewis structure of SO2 is analyzed, showing a double covalent bond where electrons are shared between sulfur and oxygen. The video explains that the small difference in electronegativity between sulfur and oxygen results in a covalent bond. The conclusion confirms that SO2 is a covalent, or molecular, compound.

What type of elements are sulfur and oxygen, which are found in SO2?

How are electrons involved in the covalent bonding of SO2?

• They are lost by both sulfur and oxygen

• They are transferred from sulfur to oxygen

• They are shared between sulfur and oxygen

• They are gained by both sulfur and oxygen

What is the significance of electronegativity in determining the bond type in SO2?

• A large difference in electronegativity leads to covalent bonding

• Electronegativity only affects ionic bonds

• A small difference in electronegativity leads to covalent bonding

• Electronegativity has no effect on bond type

What is the main reason SO2 does not form an ionic bond?
