The average bond order is the number of bonds between two atoms taking into account resonance.
a. Draw a Lewis structure for the nitrite ion and answer the questions below.
1. there are equivalent Lewis structures for NO2-.
2. the average N-O bond order is .
b. Draw a Lewis structure for sulfur dioxide and answer the questions below.
1. there are equivalent Lewis structures for SO2.
2. the average S-O bond order is _______.

Respuesta :

1. Sulfur dioxide, or SO2 , has two resonance structures which contribute equally to the overall hybrid structure of the molecule. However, a third Lewis structure can be drawn for SO2 which is more stable in theory, but doesn't quite match experimental data.

2.
