Concept explainers
(a)
Interpretation:
The electron-rich sites and electron-poor sites in the given elementary steps are to be identified.
Concept introduction:
An atom with partial or full negative charge is an electron-rich site whereas an atom with partial or full positive charge is an electron-poor site. In an elementary step, electrons tend to flow from an electron-rich site to an electron-poor site.
(b)
Interpretation:
In each of the given elementary steps, the appropriate curved arrows are to be drawn.
Concept introduction:
The curved arrow can be drawn from an electron-rich site to an electron-poor site to show the flow of electrons from the electron-rich site to the electron-poor site. The first curved arrow is drawn from the lone pair of the negatively charged atom of the electron-rich site to the less electronegative atom of the electron-poor site. The second curved arrow is drawn from the region between the less electronegative atom and more electronegative atom towards the more electronegative atom, indicating the breaking of the bond.
(c)
Interpretation:
The names of each elementary step are to be identified.
Concept introduction:
In the bimolecular substitution reaction
In nucleophilic addition step, the nucleophile adds to the polar
In the nucleophilic elimination step, the more electronegative atom bears full negative charge or partial negative charge. This electronegative atom forms a

- Nonearrow_forwardNonearrow_forwardman Campus Depa (a) Draw the three products (constitutional isomers) obtained when 2-methyl-3-hexene reacts with water and a trace of H2SO4. Hint: one product forms as the result of a 1,2-hydride shift. (1.5 pts) This is the acid-catalyzed alkene hydration reaction.arrow_forward
- (6 pts - 2 pts each part) Although we focused our discussion on hydrogen light emission, all elements have distinctive emission spectra. Sodium (Na) is famous for its spectrum being dominated by two yellow emission lines at 589.0 and 589.6 nm, respectively. These lines result from electrons relaxing to the 3s subshell. a. What is the photon energy (in J) for one of these emission lines? Show your work. b. To what electronic transition in hydrogen is this photon energy closest to? Justify your answer-you shouldn't need to do numerical calculations. c. Consider the 3s subshell energy for Na - use 0 eV as the reference point for n=∞. What is the energy of the subshell that the electron relaxes from? Choose the same emission line that you did for part (a) and show your work.arrow_forwardNonearrow_forward(9 Pts) In one of the two Rare Earth element rows of the periodic table, identify an exception to the general ionization energy (IE) trend. For the two elements involved, answer the following questions. Be sure to cite sources for all physical data that you use. a. (2 pts) Identify the two elements and write their electronic configurations. b. (2 pts) Based on their configurations, propose a reason for the IE trend exception. c. (5 pts) Calculate effective nuclear charges for the last electron in each element and the Allred-Rochow electronegativity values for the two elements. Can any of these values explain the IE trend exception? Explain how (not) - include a description of how IE relates to electronegativity.arrow_forward
