Concept explainers
(a)
Interpretation: The terms in chemistry that can be represented by underlined terms in given statement should be explained.
Concept introduction: When one single structure is unable to describe all the properties of single molecule, a phenomenon called resonance comes into play. This arises when two or more than two Lewis structures are possible for one molecule. All such structures are called resonating structures and have same placement of atoms in them but these have different locations of bond pairs and lone pairs. The resonating structures are inter-convertible with each other. The resultant of all the resonating or contributing structures is called the resonance hybrid.

- Hii. Can you help me to answer this question because i have trouble with resonance question... May you explain to me in details step by step.. Thank youuarrow_forwardRanking resonance structures Rank the resonance structures in each row of the table from major to minor. For example, in the first row, select (major) for the major resonance contributor. If two or more structures in the same row contribute equally, rank them equally by selecting the same number.
