Valence Electrons in COH2 Structure

The video tutorial explains the process of drawing the Lewis structure for COH2. It begins by identifying the number of valence electrons for each atom: carbon, oxygen, and hydrogen. The tutorial then guides the viewer through placing the atoms, forming initial bonds, and ensuring each atom achieves a full outer shell by applying the octet rule. It concludes by demonstrating how to create double bonds between carbon and oxygen to satisfy the octet rule for all atoms, resulting in a complete Lewis structure for COH2.

How many valence electrons does Carbon have in the COH2 molecule?

• 8

• 4

• 2

• 6

What is the total number of valence electrons in COH2?

• 14

• 12

• 10

• 16

Where is Carbon placed in the COH2 Lewis structure?

• Next to Oxygen

• On the outside

• Next to Hydrogen

• In the middle

Why do Hydrogens go on the outside in the COH2 structure?

• They have the most valence electrons

• They are the least electronegative

• They only need two electrons to fill their shell

• They are heavier than Carbon and Oxygen

What adjustment is made to ensure Carbon has a full outer shell?

• Add more valence electrons

• Create a double bond with Oxygen

• Remove an electron from Oxygen

• Add more Hydrogen atoms

After forming a double bond, how many valence electrons does Oxygen have?

• 6

• 8

• 10

• 12
