Chapter 3 introduced the concept of a double bond between carbon atoms, represented by C=C , with a length near 1.34 Å. The motion of an electron in such a bond can be treated crudely as motion in a one-dimensional box. Calculate the energy of an electron in each of its three lowest allowed states if it is confined to move in a one-dimensional box of length 1.34 Å. Calculate the wavelength of light necessary to excite the electron from its ground state to the first excited state.
Schrodinger and de Broglie suggested a ‘Wave—particle duality" for small particles—that is, if electromagnetic radiation showed some particle-like properties, then perhaps small punicles might exhibit same wave-like properties. Explain. How does the wave mechanical picture of the atom fundamentally differ from the Bohr model? How do wave mechanical arbitals differ from Bohr’s orbits? What does it mean to say that an orbital represents a probability map for an electron?
Using a simple particle-in-a-box model for the multiple bonding in 1,2-butadiene (see Example 4.7) and the n=2 wave function for the weakest bound electron, calculate the probability of finding the electron in an 0.1 interval centered midway between the two inner carbon atoms (that is, the center is at x=2.11 , so this interval is from x1=2.06 to x2=2.16 ). Then calculate the probability of finding the electron in an 0.1 interval centered midway between an end carbon atom and the carbon atom that is double-bonded to it in the Lewis dot structure. (You may calculate the appropriate integrals or estimate the relevant areas under the curve graphically.) Then recalculate the probabilities by approximating the integral as |( x 0)|2x , where x0 is evaluated in the middle of the range from x1 to x2 . Finally, explain why you can’t approximate the integral needed for Problem 37(a) in this way.
An electron knocked out of a molecule by passing radiation may bind to a neutral hydrogen atom making H-, with one proton and two electrons. In the ground state, will both electrons have the same energy? a) No, because the Pauli exclusion principle forbids two electrons having the same energy. b) Yes, because the Pauli exclusion principle allows a maximum of two electrons with the same energy. c) Yes, but the two electrons must have opposite spin to satisfy the Pauli exclusion principle. d) No, the Pauli exclusion principle makes both energies uncertain, so they cannot be equal.
For each of the statements below, indicate whether it is true or false and explain your reasoning. (1 sentence ) 1/ It takes more energy to ionize an electron from the 2s orbital than an electron from the 2p orbital in the Li2+ ion. 2/ The electron affinity of the Ne atom is larger than the electron affinity of the F atom. 3/ K* has a larger radius than Ar. 4/ For a diatomic molecule, in which the internuclear axis is the z-axis, the 3dz? orbital cannot mix with the 2px orbital. 5/ The internuclear distance of O2 increases as it takes an additional electron to become O2".
