Chemistry 7.2.2 Flashcards
Alkenes undergo ___ in the presence of Oxygen.
Combustion.
Why do Alkenes tend to undergo Incomplete Combustion as opposed to Complete Combustion?
Because of their higher Carbon to Hydrogen ratio.
When do Alkenes undergo Complete Combustion?
When there is excess Oxygen.
Word Equation for Complete Combustion of Alkenes:
Alkene + Oxygen —–> Carbon Dioxide + Water
When do Alkenes undergo Incomplete Combustion?
When there is Insufficient Oxygen.
Word Equation for Incomplete Combustion of Alkenes:
Alkene + Oxygen —–> Carbon Monoxide + Water
Why is Carbon Monoxide poisonous to us?
Because it gets picked up by RBC instead of Oxygen, so we die of lack of Oxygen.
What type of Alkenes is Incomplete Combustion more likely to occur in?
Higher Alkenes with larger number of Carbon Atoms.
