methane to pentane
alkanes
hydrocarbons
have only C-H bonds and C-C bonds
c-c-c-c-c
n-pentane
c-c-c-c
I
c
iso-pentane (methylbutane) boil more easily, and reacts a bit more slowly
pentanes are from
petrolem, they're liquids
if you enconter a lion on MU campus
don't run away
pentane uses
often sed as paint solvents (auto points and lacqers)
gasoline is mostly
8 carbon alkanes
spark is ignited shortly before top dead center because
it takes a while for the gas/air explosion to reach fullest extent
if the gasoline mixtre explodes too soon
the piston will be forced backwords
high octane gas explodes
slowly
low octane gas explodes
rapidly

petroleum means
rock oil (mineral oil)
man each purple bird ts huge hockers on nifty datonas
methane ethane propane butane pentane hexane heptane octane nonane decane
crude oil is pumped into frnac where it is headed and then
transferred into fractionary tower
cracking
breaking large molecules into small ones (kerosene---> gasoline)
asphalt
home heating oil
reforming
small molecules into big ones (petrolem ether-->gasoline) creates branched molecules (have high octane)
/\/\/
bond line formula (chicken wire structures)
hydrocarbons alkenes
sources for all alkenes 1. present in petroleum 2. made from alkanes
NaOH
to harden synthetic fibers
H2
to turn plant oils into shortening (crisco)
'trans'
can get closer to each other (spoon!)
natrally made bonds are
cis not trans
the oils that plants make are
molecules that contain many double bonds (because they're liquids)
The corresponding animal componds
have no doble bonds and are solid (fats)
plant oils are
corn oil, cotton oil, seed oil, olive oil, canola oil and rape seed oil.
disadvantage of double bonds
double bonds react easily and ths oils go rancid
cyclohexane is used as a
solvent for insecticides becase they are easy to make and easy to purify
tolune
solvent of a liqid paper
4 bonds to
C
3 bonds to
N
2 bonds to
O, S
1 bond to
Br, H, F, Cl
compounds with phenyl groups in them typically
have nice smells
styrene
clear plastic (champagne glasses) will crack when deformed
PVC
polyvinylchloride (pipes, sewer, water)
vinyl
house siding and upholstery
COOH
makes it an acid
esters smell and taste
nice
butyric acid
smells like human vomit (no seriously adam spilled it down the drain last year in chem and the whole school smelled like a bad night at a frat house for a week it was disgusting)
optical isomers
rotate the plane of polarized light in opposite directions
sunglasses have polarized material inthem to
minimize glare
glare is
horozontally polarized light
solutions
homogenos mixtures (same composition throughout the mixture)
mixture
non-fixed composition
solutions do not
settle-out (wine, air)
heterogenous mixtures
italian salad dressing
liquids have _ movement
more
gas
fewer molecules and takes up abot 1000 times as much space as a liquid
solvent
does the dissolving
solute
is dissolved
alloys
solutions of metals
sterling silver
92% silver 8% copper
stainless steel
iron and at least 10% chromium
lattice energy
energy needed to break apart the lattice
Svante-Arrhenius
said energy when lattice bonds are broken
temperature goes up becase energy given off
is greater than energy required
ammonim nitrate
fertilizer, also explosive
how to find concentration
(grams of solute/grams of solution) times 100%
molarity
moles of solute/liters of solution
stomach acid
0.1 M HCl
vinegar
1 M=(1 M acetic acid/1 L of vinegar)
acids
taste sour, feel tingly, react with metals to produce H2
bases
taste bitter, feel slipery
