(a)
Interpretation:
How UV-vis spectroscopy could be used to determine whether the given reaction has actually taken place or not is to be suggested with reason.
Concept introduction:
Compounds with lone pairs tend to have longer-wavelength absorptions than analogous compounds without lone pairs. The longest

Answer to Problem 15.36P
The given reaction will take place as suggested by change in the
Explanation of Solution
The given reaction is:
In the above reaction, both the reactant and product have two double bonds; in the product, both double bonds are in conjugation, but in the reactant, they are not.
Thus, we can say that the given reaction has actually occurred.
Whether the given reaction has actually taken place is suggested on the basis of conjugation in the product and its effect on

Answer to Problem 15.36P
The given reaction does not occur as given, since the
Explanation of Solution
The given reaction is:
In the above reaction, the reactant has two double bonds in conjugation, and the product has only one double bond. Thus,
Thus, we can say that the given reaction does not take place.
Whether the given reaction has actually taken place is suggested on the basis of conjugation in the product and its effect on

Answer to Problem 15.36P
The given reaction will take place as suggested by change in the
Explanation of Solution
The given reaction is:
In the above reaction, both reactant and product have three triple bonds in conjugation, but the reactant has a lone pair. So, the reactant’s longest-wavelength absorption corresponds to a
Therefore the

Answer to Problem 15.36P
The given reaction will take place as suggested by change in the
Explanation of Solution
The given reaction is:
In the above reaction, the reactant has three conjugated bonds, and the product has four conjugated double bonds.
Thus, we can say that the given reaction is actually took place.
