Question

define formal charge give the equation to calculate the formal charge​

Answer 1

Explanation:

formal charge is the charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity.

formula = valence electron -( lone pair - bonded)

Answer 2

Answer:

Formal charge is defined as the charge acquired by an atom in a molecule when all the bonding electrons are shared equally neglecting the electronegativity of the atoms present in the molecule.

It is calculated by determining the difference between the valence electrons in a free state and the number of non-bonding valence electrons with 1/2 of the total number of electrons shared in bonds.

Formula to calculate the formal change (F.C) is

F.C.= V- N- B/2

where, V = number of valence electrons

           N = no. of non-bonding valence electrons

           B = total number of shared electrons in bonds
