Transcript of Black Carbon Snake

The Black Carbon
Snake Experiment Organic Reaction Elimination Reaction Dehydration Reaction FUNDAMENTAL
CONCEPTS reactions involving organic compounds Friedrich
Wohler Addition
Elimination
Substitution water is lost Sucrose

Molecular Formula
C 12 H 22 O 11

12 CO2 + 11 H20 = sucrose + oxygen Sulfuric Acid
Molecular Formula
H 2 S O 4
•vitriol
•very polar liquid
•Excellent dehydrating agent (dried fruits)
Decomposition Carbon Concentrated Sulfuric Acid as
a Dehydrating Agent * affinity of sulfuric acid for
water is sufficiently strong Affinity ability to form compounds Redox Reaction Loss of Electrons Oxidation  Reducing Agent
Gain of Electrons  Reduction Oxidizing Agent


0 +1+6 -2 +4 -2 +4 -2 +1 -2
C + 2H2SO4 → CO2 + 2SO2 + 2H2O

C  Oxidation S Reduction Dissociation Limiting Reagent Exothermic Reactions
C12(H20)11  12C + 11H2O + Energy
The sulfuric acid evaporates making water
vapor and sulfur dioxide molecules
H2SO4 + energy  H2O + SO3
Hydrogen bonds
• A type of dipole-dipole interaction
• FON atoms
