1. Quiz 2/14/05 ionic – magnesium chloride ionic -iron (II) sulfide
Helpful Hint:
Two nonmetals:.
name with prefixes
A metal and a
nonmetal:. name
might contain a
roman numeral.
Roman numerals
are required if
there is more than
one possible charge.
Name all of the following
ionic – magnesium chloride
ionic -iron (II) sulfide
ionic - copper (II) sulfate
covalent- dinitrogen monoxide
covalent- diphosphorous trisulfide
MgCl2
FeS
CuSO4
N2O
P2S3
Go through all organic slides on Monday, 5th didn’t have a chance to write notes. We did do Lab 21 as a demo
TEST WEDNESDAY

2. Lab 21: Due Thursday Feb 17 Remember: Ionic substances conduct electricity. Covalent substances do not.
TEST Chapter 7: Wednesday Feb 16

ide, ate, ite
ide

4. Naming Organic Compounds
meth = 1
eth = 2
prop = 3
but = 4
pent = 5
hex = 6
hept = 7
oct = 8
non = 9 …
Organic compounds have one or more carbons, surrounded with hydrogens.
They may have double or triple bonds, and may include oxygen, or other atoms.
They are named by counting the “carbon backbone” and applying a prefix
“Functional Groups” provide the rest of the name.

5. 13 c page 178 cyclopropane cyclo = circle prop = 3 Carbons
6 hydrogen atoms
3 carbon atoms
cyclopropane cyclo = circle
prop = 3 Carbons
ane = no double bonds
What would this be called?

6. 13 f page 178 cyclopentane cyclo = circle penta = 5 carbons
What is this called?
5 carbon atoms
cyclopentane
cyclo = circle
penta = 5 carbons
ane = no double or triple bonds
10 hydrogen atoms

C3H8
C4H10
C5H12
C6H14
C7H16
methane

8. What would the following alkenes be called?
C2H4
C3H6
C4H8
C5H10
C6H12
C7H14
ethene
propene
butene
pentene
hexene
heptene
1oth endedhere.
Notice that there is no CH2 . Why can’t there be?
There is nothing for the carbon to double bond with!

9. Molecular and Empirical Formulas.
Molecular: adj. Pertaining to, consisting of, caused by, or existing between molecules.
Empirical: adj. 1. Relying upon or derived from observation or experiment. 2. Guided by practical experience and not theory, especially in medicine.
Formula: n 1. an established form of words for use in a ceremony or procedure. 3. Chemistry: a. a symbolic representation of the composition or of the composition and structure of a chemical compound.

11. Coefficients: How many sets of a particular compound/element
2 C5H10

12. Coefficients: How many sets of a particular compound/element
5 C5H10

13. Anatomy of a chemical formula
Coefficient = how many sets of this substance
What is the name of this compound?
How many of each atom are there?
This is the
chemical formula
for lead (II) nitrate 2
Pb(NO3)2
lead (II) nitrate
contains
1 Pb
2 NO3
Coefficient of 2 shows that there are
2 lead (II) nitrates =
2 Pb
4 N
12 O
each
NO3 contains
1 N and 3 O
since there are 2, that
is 2 N and 6 O
