alcohol. Flashcards
what are some uses of alcohol?
fuels.
solvents.
alcoholic drinks.
what can alcohol react with?
oxygen- burns well.
with sodium- fizzes (produces H₂ gas.)
with water- neutral solution.
with carboxylic acids- makes esters.
what is the names given when alcohol reacts with oxygen and what is the formula?
combustion.
C₂H₅OH+ O₂ → CO₂+H₂O (unbalanced.)
C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O (balanced.)
oxidation.
C₂H₅OH + [O] → CH₃COOH + H₂O. (unbalanced.)
C₂H₅OH + 2[O] → CH₃COOH + H₂O. (balanced.)
what is the name given when alcohol reacts with sodium and what is the formula?
C₂H₅OH + Na → C₂H₅ONa + H₂ (unbalanced.)
2C₂H₅OH + 2Na → 2C₂H₅ONa + H₂
what does [O] mean?
oxidising agent.
oxygen or acidified potassium dichromate.
fermentation of glucose: what are the raw materials involved?
sucrose/ glucose.
fermentation of glucose: what conditions are needed?
40 degrees.
anaerobic.
yeast.
fermentation of glucose: what is the waste product?
CO₂.
fermentation of glucose: what are some of the environmental issues?
can be produced from agricultural supplies of sugar beet/ cane.
land needed to grow sugar beet/ cane.
CO₂ absorbed by photosynthesis.
fermentation of glucose: economics.
lower temp= lower cost.
pressure not…..
hydration of ethene: what are the raw materials involved?
ethene.
steam.
hydration of ethene: what are the required conditions?
phosphoric acid.
300 degrees.
70 atm.
hydration of ethene: what are the waste products?
hydration of ethene: what are some of the associated environmental issues?
ethene obtained by cracking.
energy used for cracking of alkanes to obtain ethene.
hydration of ethene: economics.
cost limited to cost of crude oil.
hight temp= high cost.
high pressure= high cost.
