Concept explainers
(a)
Interpretation: The number of rings and number of pi bonds in A is to be determined. And one possible structure is to be drawn.
Concept introduction: Degree of unsaturation is used to determine the total number of rings and pi bonds present in compound by just looking at the molecular formula. It does not specify the total number of rings and total number of pi bonds individually.
(b)
Interpretation: The number of rings and number of pi bonds in B is to be determined. And one possible structure is to be drawn.
