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

c-c-c-c-c-c-c-c

n-octane

trimethylpentane

A 3,4,4 B 2,2,3

c-c-c-c-c-c

n-hexane

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
