Question

How many sigma bonds and pi bonds are in O3?

Answer 1

In ozone there are `2xxsigma` and `1xxpi` bonds.....

Explanation:

And given 18 valence electrons we typically distribute them across the 3 oxygen atoms as...

`O=stackrel(ddot)O^(+)-O^(-)`, and from left to right as you face the page there are 6, 5, and 7 valence electrons associated with each oxygen atom, and hence the given formal charges... We can see the `2xxO` `sigma` bonds, and the `pi` bond...

Of course the oxygen atoms are equivalent by resonance, and `/_O-O-O=116.8^@`, reduced from the ideal `120^@` angle because of the disproportionate influence of the lone pair electrons...
