Organic Chemistry Flashcards
1
Q
inc size of hydrocarbon
A
= inc viscosity and bp
=dec flammability
2
Q
products of complete combustion
A
carbon dioxide and water
3
Q
alkene combustion
A
- produces CO2 and water and unburnt carbon particles due to incomplete combustion
- burn in air with smoky flame
4
Q
alkene and hydrogen
A
- ALKENE + HYDROGEN -> ALKANE
- hydrogenation
- 150c + nickel catalyst
- 2 hydrogen atoms added across double bond
- double bond turns single
5
Q
alkene and water
A
- ALKENE + WATER - ALCOHOL
- hydration
- must be in steam form
- 300c, 70atm
- phosphoric acid catalyst
- reversible reaction
6
Q
alkene and halogens
A
- ALKENE + HALOGEN -> DI(halogen)(alkene)ANE
ethene + chlorine -> dichloroethane
7
Q
Fermentation of sugar
A
glucose —-> (yeast) (30c) ethanol + carbon dioxide
must take place in anaerobic conditions
8
Q
alcohol and water
A
- soluble in water + form neutral solutions
- inc carbon atoms = dec solubility
9
Q
alcohol and sodium
A
ethanol + sodium -> sodium ethoxide + hydrogen
10
Q
alcohol and oxidising agent
A
produces carboxylic acid and water
11
Q
combustion of alcohols
A
produces carbon dioxide and water
12
Q
carboxylic acid and metal carbonate
A
metal _anoate + CO2 + H2O
13
Q
carboxylic acid and alcohol
A
ester + water
ethyl ethanoate
