Question

In O3 molecule. the formal charge on the central O-atom is

Answer 1

Answer:

−1,0,1

Explanation:

A formal charge is equal to the number of valence electrons of an atom MINUS the number of electrons assigned to an atom.

Consider the resonance structures for O3.

Oxygen has 6 valence electrons. Look at the top left oxygen atom. It has two lone pairs (4electrons) and a double bond (2 electrons).

Even though a double bond contains 4 electrons total and is counted as such when seeing that oxygen's octet is filled, 2 electrons belong to each oxygen and they are shared among the two.

Let's examine the top resonance structure:

Left: 6 valence −6 assigned =0 formal charge
Center 6 valence −5 assigned =1 formal charge
Right: 6 valence −7 assigned =−1 formal charge

Notice that even though the atoms have varying formal charges, the overall charge of O3 is the sum of the formal charges in the molecule: 0+1+(−1)=0.

Ions' formal charge sums are ≠0.
