Can someone help me with this please it's for friday? We are giving the VSEPR theory. I give 100 points.

Sulfite ion has a shorter

S-O

bonds.

Explanation:

The Lewis structure of

SO

3

is

SO3

SO3

(from chemistry.stackexchange.com)

It has a total of six σ and π bonds to the three

O

atoms.

The average bond order of an

S-O

bond is

6

3

=

2

.

The Lewis structure of

SO

2

−

3

is

It is a resonance hybrid, with a total of four σ and π bonds to the three

O

atoms.

The average bond order of an

S-O

bond is

4

3

≈

1.33

.

Since bond length decreases as bond order increases,

SO

3

is predicted to have the shorter bond length.
