C471 Quiz 3 Fall 2001

 

A = True  B=False

 

1. Citation indexes provide a means for a searcher to retrieve newer materials that cite a known publication.  Unfortunately, the IU access to Web of Science only goes back as far as 1987, so this technique would not work for a known work that was published in 1985.

 

2. SciFinder Scholar includes references to more new journal articles than does Science Citation Index (Web of Science), but SCI has much broader coverage of new chemistry patents than does SFS.

 

3. On Beilstein CrossFire, it is possible to identify compounds with structures that show the stereochemistry of the molecules.

 

4. Whether doing a subject or chemical name search in the Chemical Abstracts printed volume or collective indexes, the first step should always be to consult the CA Index Guide for the time period being searched in order to locate the proper term.

 

5. Finding the registry number for a compound is very important when searching in the online Chemical Abstracts files because the indexing of the chemical substances in the documents in the CA or CAPlus files utilizes mostly registry numbers, instead of chemical names.

 

6. Which of the following types of substructure searches are possible in the STN Registry File:

 

A. Exact search

B. Family search

C. Closed substructure search

D. Full substructure search

E. Any of the above

 

7. In a structure search on SciFinder Scholar, it is possible to have variability at a specific node for the atoms, but you cannot have variable shortcut symbols at a given node.

 

8. One major reason to use NLM's ChemID database in preference to SciFinder Scholar or STN Express to find information on a chemical substance is that ChemID is free.

 

9. Assuming that the printed Chemical Substance Index name for Flavan is:

 

2H-1-Benzopyran, 3,4-dihydro-2-phenyl-

 

you should look in the "H" volume of the Chemical Abstracts CSI in order to find information about the compound.

 

10. Look only at the individual formulas below and answer the following question:

 

A. ClH

B. BrH

C. CHNO

D. H2SO4

E. C2Br2F2

 

Which one of these formulas is out of order according to the rules of the Hill System?
