Lewis Structure of CH3COO-

The video tutorial explains the process of drawing the Lewis structure for the acetate ion (CH3COO-). It begins by identifying the total number of valence electrons and arranging the atoms. The tutorial then demonstrates how to place electrons between atoms to form chemical bonds and complete the octet for each atom. It highlights the need to adjust electron placement to ensure all atoms satisfy the octet rule, including forming a double bond between carbon and oxygen. The video concludes with the final Lewis structure for the acetate ion.

How many total valence electrons are present in the CH3COO- Lewis structure?

• 18

• 24

• 30

• 36

In the initial arrangement of the CH3COO- Lewis structure, which atoms are placed next to each other?

• Oxygens

• Carbons

• Hydrogens

• Nitrogens

What is the purpose of placing two electrons between atoms in the CH3COO- Lewis structure?

• To increase the energy level

• To form chemical bonds

• To form ionic bonds

• To complete the octet

Which atom initially does not satisfy the octet rule in the CH3COO- Lewis structure?

• Hydrogen

• Carbon on the left

• Oxygen

• Carbon in the middle

How is the octet rule satisfied for the middle carbon atom in the CH3COO- Lewis structure?

• By removing electrons from oxygen

• By adding more hydrogen atoms

• By forming a triple bond with oxygen

• By sharing electrons to form a double bond with oxygen

What is the final structure called after completing the octet rule for all atoms in CH3COO-?

• Sulfate ion

• Nitrate ion

• Carbonate ion

• Acetate ion
