Class of: 15-Feb-2016.
Today we covered Section 7.4: Molecular Compounds: Chemical Formulas and Naming (p. 192).
Learning Objectives:
- Students will be able to name a molecular compound given the chemical formula, and produce the chemical formula given the name.
As it turns out, there is a system for naming molecular compounds that require prefixes above 10. The problem is that the naming conventions get very complicated. The prefix for 11 is “undeca-,” 12 is “dodeca-,” and 13 is “trideca-.” Not so bad, but when you get to 31 the prefix is “hentriacontra-.” Ew.
Some other notable examples: 1000 is “kilia-” and 2000 is “dilia-.” What’s the dilia with that??
We have a small quiz on Wednesday, 17-Feb-2016 on Chapter 7!
We have a lab tomorrow on Tuesday, 16-Feb-2016! Please read the Chapter 7 lab post above and prepare answers to the pre-lab questions by then!
Please work through the following review problems if you did not already finish them during class:
