(a)
Interpretation:
The neutron-to-proton ratio for tin-134 to be calculated.
Concept introduction:
Primary factor that determines an atom’s stability is its ratio of neutrons to protons. Atoms emit beta and alpha particles and these emissions affect neutron-to-proton ratio of newly generated nucleus.
Answer to Problem 50A
Neutron-to-proton ratio for tin-134 is 84 to 50.
Explanation of Solution
(b)
Interpretation:
The neutron-to-proton ratio for silver-107 to be calculated.
Concept introduction:
Primary factor that determines an atom’s stability is its ratio of neutrons to protons. Atoms emit beta and alpha particles and these emissions affect neutron-to-proton ratio of newly generated nucleus.
(b)
Answer to Problem 50A
Neutron-to-proton ratio for silver-107 is 60 to 47.
Explanation of Solution
Atomic number of silver is 47 and protons that present in silver are 47. Thus number of neutrons present in silver-107 is, 107-47 = 60. Therefore neutron-to-proton ratio for silver-107 is 60 to 47.
(c)
Interpretation:
The neutron-to-proton ratio for carbon-12 to be calculated.
Concept introduction:
Primary factor that determines an atom’s stability is its ratio of neutrons to protons. Atoms emit beta and alpha particles and these emissions affect neutron-to-proton ratio of newly generated nucleus.
(c)
Answer to Problem 50A
Neutron-to-proton ratio for carbon-12 is 6 to 6.
Explanation of Solution
Atomic number of carbon is 6 and protons that present in carbon are 6. Thus number of neutrons present in carbon-12 is, 12-6 = 6. Therefore neutron-to-proton ratio for carbon-12 is 6 to 6.
(d)
Interpretation:
The neutron-to-proton ratio for carbon-14 to be calculated.
Concept introduction:
Primary factor that determines an atom’s stability is its ratio of neutrons to protons. Atoms emit beta and alpha particles and these emissions affect neutron-to-proton ratio of newly generated nucleus.
(d)
Answer to Problem 50A
Neutron-to-proton ratio for carbon-14 is 8 to 6.
Explanation of Solution
Atomic number of carbon is 6 and protons that present in carbon are 6. Thus number of neutrons present in carbon-14 is, 14-6 = 8. Therefore neutron-to-proton ratio for carbon-14 is 8 to 6.

- Post Lab Questions. 1) Draw the mechanism of your Diels-Alder cycloaddition. 2) Only one isomer of product is formed in the Diels-Alder cycloaddition. Why? 3) Imagine that you used isoprene as diene - in that case you don't have to worry about assigning endo vs exo. Draw the "endo" and "exo" products of the Diels-Alder reaction between isoprene and maleic anhydride, and explain why the distinction is irrelevant here. 4) This does not hold for other dienes.
