Concept explainers
Interpretation:
The resonance structure from most significant to least significant has to be ranked.
Concept Introduction:
The unshared electrons are called lone pair.
A negative charge means two lone pairs means and a positive charge means one lone pair
Curved arrows are necessary in drawing the resonance structure.
Curved arrows has a head indicating that the electrons are coming and tail indicating that the electrons are going.
The two rules in drawing the resonance structure is,
- Breaking of single bond is not allowed.
- Never exceed an octet for second row elements.
When a single Lewis structure does not represent a structure adequately, the true structure is the intermediate between the two or more structure referred to as resonance structure.
Octet rule-The atoms tend to gain, lose, share electrons until they are surrounded by 8 valence electrons or 4 electron pair.
