The energy diagram for the given S N 2 reaction and the structure of transition state is to be drawn. The axes, starting material and product are to be labeled. Concept introduction: The replacement or substitution of one functional group with another different functional group in any chemical reaction is termed as substitution reaction. The graphical representation of chemical reaction in which x-axis represents energy of the reaction and y-axis represents the reaction coordinate is called energy profile diagram.

Question

The electron of a hydrogen atom is excited to the 4d orbital. Calculate the energy of the emitted photon if the electron were to move to each of the following orbitals: (a) 1s; (b) 2p; (c) 2s; (d) 4s. (e) Suppose the outermost electron of a potassium atom were excited to a 4d orbital and then moved to each of these same orbitals. Describe qualitatively the differences that would be found between the emission spectra of potassium and hydrogen (do not perform calculations). Explain your answer.

Imagine a four-dimensional world. In it, atoms would have one s orbital and four p orbitals in a given shell. (a) Describe the shape of the Periodic Table of the first 24 elements. (b) What elements would be the first two noble gases (use the names from our world that correspond to the atomic numbers).

The electron affinity of thulium was measured by a technique called laser photodetachment electron spectroscopy. In this technique, a gaseous beam of anions of an element is bombarded with photons from a laser. The photons knock electrons off some of the anions, and the energies of the emitted electrons are detected. The incident radiation had a wavelength of 1064 nm, and the emitted electrons had an energy of 0.137 eV. Although the analysis is more complicated, we can obtain an estimate of the electron affinity from the energy difference between the photons and the emitted electrons. What is the electron affinity of thulium in electron volts and in kilojoules per mole?
