Understanding Lewis Structures for Formaldehyde

What is the primary characteristic of non-metals that allows them to form molecular compounds?

• They have high melting points.

• They are good conductors of electricity.

• They share electrons.

• They have metallic luster.

How many valence electrons does carbon contribute when drawing the Lewis structure for formaldehyde?

• Eight

• Four

• Two

• Six

In the initial Lewis structure for formaldehyde, which atom is placed at the center?

• Hydrogen

• Oxygen

• Carbon

• Nitrogen

What is the total number of valence electrons used in the Lewis structure of formaldehyde?

• Sixteen

• Ten

• Twelve

• Fourteen

How is the octet rule satisfied for the central carbon atom in formaldehyde's Lewis structure?

• By adding more hydrogen atoms

• By forming a triple bond with oxygen

• By moving lone pairs from oxygen to form a double bond

• By adding extra electrons to carbon
