Concept explainers
Interpretation:
The greatest resonance contributor to the resonance hybrid has to be determined from the following resonance structures.
Concept Introduction:
The unshared electrons of an atom that does not involve in bonding are called 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.
Most stable structure contributes most to the resonance hybrid.
