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

Pa=XaPa; Pb=XbPb; Pa+Pb=Ptotal
