Term
Adhesion
Definition
the attraction of unlike molecules; Example: water clings to plant vessel walls- counteracts pull of gravity
Term
Alcohol Group
Definition
Hydroxal group- hyrdogen bonded to oxygen; polar
Term
Aldehyde group
Definition
carbonyl group- carbon double bonded to oxygen; polar; ex-sugar
Term
Amine group
Definition
nitrogen atom bonded to 2 hydrogen atoms and to a carbon skeleton; helps form proteins
Term
buffer
Definition
minimizes changes in PH when extraneous acids or bases are added to a solution
Term
buffer
Definition
minimizes changes in PH when extraneous acids or bases are added to a solution
Term
Carbonal group
Definition
carbon atom double bonded to an oxygen atom
Term
Carboxyl Group
Definition
carbon atom doubled bonded to an oxgygen atom and alsoe binded to a hydroxl group
Term
Cohesion
Definition
attraction of like molecules;
Term
Evaporative Cooling
Definition
liquid changes to gas, taking away the kinetic energy of a surface, making it become cool
Term
Functional Group
Definition
part of the ogranic compound entering into a reaction
Term
Geometric Isomer
Definition
compounds with seame molecular formuals but have different shapes becasue of the inflexibility of double bonds
Term
Hydrophilic
Definition
water loving
Term
Hydrophobic
Definition
water fearing (does not mix with water)
Term
Ketone
Definition
Carbon atom is bounded to two other carbons, but not at the end of a carbon skeleton; polar
Term
Mole
Definition
molecule weight of a substance in grams; contains avagadro's number
Term
organic chemistry
Definition
study of carbon compounds
Term
PH scale
Definition
ranges from 0-14; PH concentration =-log[h]
Term
phosphate group
Definition
important in energy transfer; phosphate ion convalently attached by one of its oxygen atoms to the carbon skeleton
Term
Solute
Definition
substance that is dissolved in a solution
Term
Specific heat
Definition
heat that must be absorbed or lost for 1g of a substance to change its temp by 1c
Term
Structural Isomer
Definition
Compounds with the same formular, but the arrangement of their atoms is different so they ahve different properties
Term
Sulfhydryl Group
Definition
A sulfur atom bonded toa hydrogen atom
Term
Surface tension
Definition
type of cohesion; measure of how difficult it is to break the surface of a liquid
