1) An element is to a(n) ___________ as an organ is to a(n) _______________
Answer - b - compound; organism
2) In the term trace element, the modifier trace means
Answer - a - the element is required in very small amounts.
3) Compared to 31P, the radioactive isotope 32P has
Answer - b - one more neutron
4) Atoms can be represented by simply listing the number of protons, neutrons, and electrons - for example, 2P+; 2n0; 2e- for helium. Which atom represents the 18O isotope of oxygen?
Answer - b - 8p+; 10n0; 8e-
5) The atomic umber of sulfur is 16. Sulfur combines with hydrogen sulfide. Based on the electron configuration of sulfur, we can predict that the molecular formula of the compound will be
Answer - c - H2S.

5) Choose the term that correctly describes the relationship between these two sugar molecules:
Answer - a - structural isomers.
6) Identify the asymmetric carbon in this molecule:
Answer - b -
7) Which functional group is not present in this molecule?
Answer - b - sulfhydryl.
8) Which action could produce a carbonyl group?
Answer - a - the replacement of the hydroxyl of a carboxyl group with hydrogen.
9) Which functional group is most likely to be responsible for an organic molecule behaving as base?
Answer - d - amino.
10) Given what you know about the electro negativity of oxygen, predict which of the following molecules would be the strongest acid. Explain your answer.
Answer - b -
The molecule in choice b would be the strongest acid because the oxygen bonded to carbon in choice b, the carbonyl group as opposed to two hydrogen atoms bonded to a carbon in choice a would make the covalent bond between oxygen more polar and therefore would give the molecule more acidic properties than the molecule shown in choice a.
