Term
addition reaction
Definition
a reaction in which a compound adds to a multiple bond.
Term
alkane
Definition
a hydrocarbon that contains only single bonds
Term
alkene
Definition
a hydrocarbon that contains one or more double bonds.
Term
alkyl halide
Definition
a derivative of an alkane in which one or more hydrogens are replaced by halogens.
Term
alkyne
Definition
a hydrocarbon that contains one or more triple bonds.
Term
alpha
Definition

4a

2   

helium nucleus, emitted when the nucleus is too big.

Term
aromatic
Definition
best represented by benzene (6 carbon ring, 3 alternating double bonds)
Term
beta
Definition

identical to a electron, emitted from the nucleaus when a nucleus has too many protons.

*when a neutron is changed into a proton and an electron.

Term
breeding/breeder
Definition

a nuclear reaction in which isotopes that will not undergo spontaneous fission are changed into isotopes that will.

(as it generates heat it also creates new elements)

Term
combustion
Definition
rapid oxidation accompanied by heat and, usually, light 
Term
covalent
Definition
the atrractive force that results between two atoms that are both attracted to shared pair of electrons.
Term
critical
Definition
a constant rate chain reaction
Term
cycloalkane
Definition

(dog chasing it's tail)

a alkane in which carbon atoms form a ring.

Term
fission
Definition

(splitting)

process in which large nuclei split into smaller equal sized nuclei when bombarded by neutrons.

Term
fusion
Definition

(fusing)

a process in which small nuclei combine or fuse to form large nuclei.

Term
half-life
Definition
the time required for one half the unstable nuclei in a sample to undergo radioactive decay.
Term
halogenation
Definition

addition of a halogen (F,Cl,Br, I)

will result in the formation of an dialkyl halide

Term
hydration
Definition

the addition of water to a mutilple bond.

(1 carbon gets the H, the other gets the OH)

*produces an alcohol.

Term
hydrocarbon
Definition
an organic compound that contains only one carbon and one hydrogen.
Term
hydrogenation
Definition
a reaction in which the addition of hydrogen takes place.
Term
hydrohalogenation
Definition

addition of HX to an alkene

(add hydrongen (H) to a halogen (X) F,Cl,Br,I

=HF,HCl,HBr,HI

Term
ionic
Definition
the attractive force that holds together ions of opposite charge.
Term
isomer
Definition

 a compound displaying isomerism with one or more other compounds.

*different arrangements on the carbon chain either geometrical or structural.

Term
organic
Definition
carbon containing compounds
Term
parent
Definition
Term
phenyl
Definition
a benzene ring with one hydrogen absent
Term
positron
Definition
a positively charged electron
Term
saturated
Definition

(Alkanes)

organic compound in which carbon is bonded to 4 other atoms by single bonds (no double or triple bonds!!)

Term
unsaturated
Definition

(Alkenes,Alkynes, and Aromatics)

contain double bonds, triple bonds or 6 carbon rings.

Term
supercritical
Definition
a branching chain reaction.
