C1
- Types of hydrocarbons
- Alkanes
- Saturated
- Single covalent
bonds
- CnH2n+2
- Alkenes
- Unsaturated
- One or more double covalent bonds
- CnH2n
- Unsaturation/bromine test
- Reaction will break the c=c and add bromine
- Bromine water + Alkene -----> reaction (dibromo compound colourless)
- There will be no reaction with alkanes as there are no spare bonds
- Br water + Alkane ----> no reaction (orange)
- Emulsifiers
- Emulsifiers are substances that help water and oil mix without seperating
- Molecules have a hydrophilic head
- Water
- Joins the mixture
- Hydrophobic tail
- Oil
- Cooking Egg
- Egg -----> proteins change shape (denatured)
- The changes in the white : Thick colourless ----> white solid
- Combustion of Methane
- When fuel reacts with oxygen they burn to release useful heat energy; however it requires a stable supply
- Complete
- Uncomplete
- Methane (2CH4) +Oxygen(3O2)---->Carbon Monoxide (2CO) + Water (4H2O)
- Methane (CH4) + Oxygen (O2) -----> Carbon (C) + Water (2H2O)
- CH4(Methane)+2O2(Oxygen)---->CO2(Carbon Dioxide+2H2O(Water)
