CHEM134 C001 SPRING DIGITAL ACID
BASE CHEMISTRY BEYOND LABZ
COMPLETE QUESTIONS AND ANSWERS
GRADED A+
◉ volatility
Answer: substance's tendency to vaporize
◉ frequency factor (in the Arrhenius Equation)
Answer: Number of times the reactants approach the activation
barrier per unit time
◉ elementary step
Answer: A step within the reaction mechanism, which cannot be
broken down into smaller steps. The molecularity of the step can
be linked to a rate law (i.e. first order, second order, zero order)
◉ catalyst
Answer: substance that increases the rate of reaction without
being consumed
◉ what does the equilibrium constant represent
,Answer: the relationship between products and reactants of a
reaction at equilibrium
◉ amphoteric substances
Answer: Substances that can react as both acids and bases, such
as H20 and NH3
◉ strong acids
Answer: HCl, HBr, HNO3, H2SO4, HClO4
◉ weak acids
Answer: carboxylic acids, acetic acid, hydrofluoric acid
◉ strong bases
Answer: NaOH, KOH
◉ weak bases
Answer: NH3, amines (anything with NH2)
◉ functional group
Answer: group of atoms within a molecule having characteristic
chemical behavior
◉ alkanes
, Answer: saturated, single bonds
◉ alkenes
Answer: have unsaturated, double bonds
◉ alkynes
Answer: have unsaturated, triple bonds
◉ arenes
Answer: have alternating double/single bonds, often in an
"aromatic ring"
benzene is an example
◉ alcohol
Answer: carbon atom bonded to oxygen of hydroxyl group (-OH)
polar, water soluble
increasing hydrocarbon size decreases solubility
◉ carboxylic acid
Answer: -OH group bonded to C and O double bond
