To calculate the formal charge of each atom in the CH3COOH molecule, we can use the formula:Formal charge = Valence electrons - Non-bonding electrons - 1/2 Bonding electrons The CH3COOH molecule can be represented as CH3-COOH. Let's break it down into individual atoms and calculate their formal charges:1. Carbon C1 in CH3:Valence electrons: 4 for carbon Non-bonding electrons: 0 all electrons are involved in bonding Bonding electrons: 8 4 single bonds with 3 hydrogens and 1 carbon Formal charge = 4 - 0 - 1/2 8 = 4 - 4 = 02. Hydrogen H in CH3:Valence electrons: 1 for hydrogen Non-bonding electrons: 0 all electrons are involved in bonding Bonding electrons: 2 1 single bond with carbon Formal charge = 1 - 0 - 1/2 2 = 1 - 1 = 03. Carbon C2 in COOH:Valence electrons: 4 for carbon Non-bonding electrons: 0 all electrons are involved in bonding Bonding electrons: 8 1 single bond with C1, 1 single bond with O, and 1 double bond with O Formal charge = 4 - 0 - 1/2 8 = 4 - 4 = 04. Oxygen O1 in COOH with single bond:Valence electrons: 6 for oxygen Non-bonding electrons: 4 2 lone pairs Bonding electrons: 2 1 single bond with C2 Formal charge = 6 - 4 - 1/2 2 = 6 - 4 - 1 = 15. Oxygen O2 in COOH with double bond:Valence electrons: 6 for oxygen Non-bonding electrons: 4 2 lone pairs Bonding electrons: 4 1 double bond with C2 Formal charge = 6 - 4 - 1/2 4 = 6 - 4 - 2 = 06. Hydrogen H in COOH:Valence electrons: 1 for hydrogen Non-bonding electrons: 0 all electrons are involved in bonding Bonding electrons: 2 1 single bond with O1 Formal charge = 1 - 0 - 1/2 2 = 1 - 1 = 0So, the formal charges of the atoms in the CH3COOH molecule are:C1: 0H in CH3 : 0C2: 0O1 single bond : +1O2 double bond : 0H in COOH : 0The significance of the formal charges in this molecule is that they help to determine the stability and reactivity of the molecule. In this case, the oxygen atom with a formal charge of +1 indicates that it is more reactive and can participate in chemical reactions, such as donating a proton H+ in acidic conditions. This is consistent with the acidic nature of acetic acid CH3COOH .
