Concept explainers
(a)
Interpretation:
An efficient synthesis that can be used to achieve each of the following transformations is to be determined.
Concept introduction:
The product molecule has one more carbon atom than the starting material. For the generation of tertiary alcohol from secondary alcohol, there must be oxidation of alcohol to the carbonyl group, after which, there must be an addition of a methyl fragment, preferably using a Grignard reagent. This after hydrolysis can yield the desired tertiary alcohol.
(b)
Interpretation:
An efficient synthesis that can be used to achieve each of the following transformations is to be determined.
Concept introduction: The final product has one more carbon atom than the starting material. This can be facilitated by the addition of a methyl group, preferably using a Grignard reagent after conversion of
(c)
Interpretation:
The efficient synthesis that can be used to achieve the following transformation is to be determined.
Concept introduction:
The final product contains two additional carbon atoms, so the synthesis requires a carbon-carbon bond-forming reaction. To facilitate this, the desired product should be produced by oxidizing the generated alcohol using the proper Grignard reagent.
(d)
Interpretation:
The efficient synthesis that can be used to achieve each of the following transformations is to be determined.
Concept introduction:
The target molecule contains one additional carbon atom, so the synthesis must have a carbon-carbon bond-forming reaction. This can be achieved by using a Grignard reagent followed by an elimination reaction which can yield the desired unsaturated product.
(e)
Interpretation:
The efficient synthesis that can be used to achieve each of the following transformations is to be determined.
Concept introduction:
The target molecule contains three additional carbon atoms, so the reaction needs a Carbon−Carbon bond-forming reaction. The
(f)
Interpretation:
An efficient synthesis that can be used to achieve each of the following transformations is to be determined.
Concept introduction:
The target molecule has two additional phenyl groups, which can be done by adding Grignard reagent containing phenyl groups two times, followed by oxidation. The starting material contains carbonyl carbon which is the reaction center for the phenyl part of the Grignard reagent.

- Clouds of hot, luminous interstellar hydrogen gas can be seen in some parts of the galaxy. In some hydrogen atoms, electrons are excited to quantum levels with n = 100 or higher. (a) Calculate the wavelength observed on Earth if the electrons fall from the level with n = 100 to one with n = 2. (b) In what series would this transition be found? (c) Some of these high-energy electrons fall into intermediate states, such as n = 90. Would the wavelengths of a transition from the state with n = 100 to one with n = 90 be longer or shorter than those in the Balmer series? Explain your answer.arrow_forwardIn the spectroscopic technique known as photoelectron spectroscopy (PES), ultraviolet radiation is directed at an atom or molecule. Electrons are ejected from the valence shell and their kinetic energies are measured. Since the energy of the incident ultraviolet photons is known and the kinetic energy of the ejected electron is measured, the ionization energy, I, can be deduced because total energy is conserved. (a) Show that the velocity, v, of the ejected electron and the frequency, n, of the incident radiation are related by hv = I + (1/2)mv^2? (b) Use this relation to calculate the ionization energy of a rubidium atom, knowing that light of wavelength 58.4 nm produces electrons with a velocity of 2,450 km/s Recall that 1 J = 1 kg.m^2/s^2arrow_forwardI) In Millikan's experiment, each droplet observed by the technicians contained an even number of electrons. If they had been unaware of this limitation, how would it have affected their report of an electron's charge?II) Millikan measured the charge of an electron in electrostatic units, esu. The data he collected included the following series of charges found on oil drops: 9.60 X 10^-10 esu, 1.92 X 10^-9 esu; 2.40 X 10^-9 esu; 2.88 X 10^-9 esu; and 4.80 X 10^-9 esu. (a) From this series, find the probable charge of the electron in electrostatic units. (b) Estimate the number of electrons in an oil drop with a charge of 6.72 X 10^-9 esu. The actual charge (in Coulombs) of an electron is 1.602 X 10^-19 C. What is the relationship between esu and Coulombs?arrow_forward
