Cards

Term
Alcohol
Definition
An O-H bonded to a carbon atom. Because of hydroxyl (-OH) group, alcohols are polar. Naming : They end in -ol.
Term
Halides
Definition
A halogen bonded to a carbun atom. End in the -ide (in suffixes) or -o (in prefixes)
Term
Carboxylic Acids
Definition
A carboxyl group (COOH) bonded to a carbon chain. H dissociates, making these molecules acidic. They end it -ic acid.
Term
Amines
Definition
NH2 bonded to a carbon atom. Since it is similar to ammonia, it's molecules are basic. It ends in -amine
Term
Aldehydes
Definition
A carbonyl (C=O) group bonded to a terminal carbon. They end in aldehyde.
Term
Ketones
Definition
A carbonyl (C=O) that is bonded to a nonterminal carbon
Term
Ethers
Definition
An oxygen atom links to hydrocarbon chains. They end in ether
Term
Esters
Definition
An ester is essentially a ketone and an ether put together. They end in -ate
Term
Addition
Definition
A carbon-carbon double bond gets broken into a single bond with the addition of
Term
Substitution
Definition
One atom or a group of atoms are replaced with another atom or group. This rarely happens.
Term
Polymerization
Definition
Two smaller compounds called monomers are joined to form a third larger compound.
Term
Cracking
Definition
A larger compound is broken down into smaller compounds
Term
Oxidation
Definition
Combustion (CxHxOx + XO2-- XCO2 + H2O
Term
Esterification
Definition
Organic acid reacts with an alcohol to produce an ester and water.
Term
Fermentation
Definition
An organic compounds in the absence of oxygen to produce an alcohol and carbon dioxide
Term
Lipids
Definition
A long, branching chain made up of carbon, hydrogen, and oxygen. They are generally fats and oils. They are not soluable in water and instead aggregate and form droplets.
Term
Triglycerides
Definition
A lipid made up of long fatty (hydrocarbon) chains, that is headed with glycerol.
Term
Phospholids
Definition
The lipids that form cell walls
Term
Carbohydrates
Definition
Also known as sugars, they form carbon, hydrogen, and oxygen chains (in a 1:2:1 ratio.) They are polymers made of sugar monomers.
Term
Monosaccharides
Definition
Simple carbohydrates such as glucose and fructose with just one unit of sugar.
Term
Polysaccharides
Definition
Larger carbohydrates that store energy in plants and animals (cellulose).
Term
Nucleic Acids
Definition
Made up of carbon, hydrogen, oxygen, nitrogen, and phosphorus, nucleic acids are polymers made up of monomers called nucleotides. They make up DNA and RNA
Term
Proteins
Definition
Polymers made up of amino acid monomers which are made up of aminos and carboxyls.
Term
Polypeptides
Definition
Chains of linked amino acids.
Term
Enzymes
Definition
Biological catalysts which are proteins.
Term
What is earth's air made up of?
Definition
78% Nitrogen, 20% Oxygen, <1% Argon, <1% Other, Water Vapor (Variable)
Term
Give the order of the regions in the earth's atmosospher.
Definition
From inside to out, troposphere, stratosphere, mesosphere, and thermosphere.
Term
Photodissociation
Definition
The process in which a bond is broken and absorbs a photon of light. In this case, O2 (g) + (gamma rays) -- 2O(g), then from 0(g) + 02(g)--03
Term
Chloroflourocarbons
Definition
A compound that reacts with light energy to form free chlorine which bonds with the oxygen, thus making it unable to turn into ozone
Term
Acid rain
Definition
Rain that has an abnormal pH. The formula is S03(g)+ H20(l)--H2SO4
Term
Carbon Monoxide
Definition
CO binds irreversibly to hemoglobin and makes it unable to transport oxygen.
