Bookmarks People Window Help u/courses/69086/quizzes/81233/take D Question 33 1 pts A scientist proposes a nucleophilic substitution reaction in which the reactant, anion nucleophile has a pKabH of -8.4 and the product anion (which was the leaving group) has a pKabh of -7.1. The proposed reaction represents apKabH unit climb. Report your answer to the nearest tenth of a unit. D Question 34 1 pts Use the quantized energy expression of a "particle in a box" for the following problem. Imagine a "linear" conjugated molecule that has a length of 592 pm. To the nearest ones, what is the wavelength of EM radiation (in nm) that will excite a pi electron from n = 4 to the next higher quantum level (ie, n-4

Explanation / Answer

(33)

Using the following relation:

pKabH unit climb for the reaction = pKabH of reactant anion - pKabH of product anion = 8.4-7.1 = 1.3
