Question

Write the formal charge on atom with example

Answer 1

Answer:

Formal Charge = [# of valence electrons on atom] – [non-bonded electrons + number of bonds]. Let's apply it to some examples. for example BH4 (top left corner).

...

The number of valence electrons for carbon is 4.

The number of non-bonded electrons is two (it has a lone pair)

The number of bonds around carbon is 3.

In shot....

formal charge (FC) 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.
