Covalent - ANSWER-When 2 atoms "share" electrons
Empirical Formula - ANSWER-The lowest whole # ratio of atoms in a compound
Molecular Formula - ANSWER-The actual number of atoms in a compound
Homologous Series - ANSWER-The series of hydrocarbons that follows the formula
C(n)H(an+b)
Hydrocarbon - ANSWER-A compound composed entirely of hydrogen and carbon
Alkanes - ANSWER-A carbon chain that contain only single bonds
Catenation - ANSWER-Adding carbons to chain
Isomer/Structural Isomer - ANSWER-A molecule with a different structure but the same
chemical formula
Straight chain carbon - ANSWER-a hydrocarbon with no branches
Branched chain carbon - ANSWER-a carbon chain that has branches
Substitution reaction - ANSWER-When an H on the carbon chain is switched out for a
substituent group or functional group
, Free Radical - ANSWER-An unbonded atom that can accept an extra electron to make
a bonding pair
Initiation - ANSWER-when the # of free radicals INCREASE
Propagation - ANSWER-when the # of free radicals STAY CONSTANT
Termination - ANSWER-when the # of free radicals DECREASE
Homolytic Fission - ANSWER-The process of braking apart one molecule to create two
identical atoms or molecules that acts as free radicals
Chain Reaction - ANSWER-when a small event causes many subsequent events to
occur
Reaction Mechanism - ANSWER-The series of steps needed to go from reactants to
products within an organic reaction
Alkene - ANSWER-When there are double bonds within the carbon chain
Saturated - ANSWER-when all the spots for hydrogen are filled
Unsaturated - ANSWER-When the carbon chain has double bonds preventing all the
spots for hydrogen from being filled
Addition Reaction - ANSWER-When two organic compounds are added together to
make a singular compound. Involves increasing the size of the carbon chain
Electrophiles - ANSWER-positively charged species that are attracted to high
concentration electron environments
