F U C K CHEM
Exhaled air over cell; if ethanol then it is oxidized to ethanoic acid
C2H5OH + H20 --> CH3COOH + 4H +4e
Overall oxidation reaction
C2H5OH + O2 --> CH3COOH + H20
Low volatility
High IMF; High boiling point; increasing molecule size
volatility of functional groups (most to least)
amide>carboxyl>hydroxyl>ketone>aldehyde>amino>ester>ether
breathalyzer
chromate (VI) to chromate (III); orange to green color change
Mass Spec
confirm presence of compound using peek of parent ion
Alcosensor
electrochemical process in a fuel cell to measure ethanol concentration
detection of ethanol
ethanol's hydroxyl group is soluble in water and circulates through the body
Fractional distillation
evaporation and condensation in a fractioning column
anabolic steroids
hormones that promote tissue growth
H2O solvent
large polar functional groups; H-Bonding
Steroid
lipid molecule with four fused carbon rings
Mole fraction formula (Xa or Xb)
moles of solute/total moles of solution
Hexane and benzene solvent
nonpolar; high hydrocarbon
Use of fractional distillation
separates a solution usually phenols and toluene
Gas Chromatography
stationary phase and mobile phase
Ethanol
volatile compound; equilibrium in lungs between solution and blood/gas
High volatility
Low IMF; Low boiling point; decreasing molecule size
Raoult's Law Equation
