C7 - Organic Chemistry Flashcards
Why are Alkanes saturated compounds
Each carbon atom forms four single covalent bond
Equation for Methane
CH.4
Equation for Ethane
C.2H.6
Equation for Propane
C.3 H.8
Equation for Butane
C.4H.10
Properties of Shorter carbon chain
More viscous
Lower boiling points
More flammable
Why are hydrocarbons used as fuels
Due to releasing large amounts of energy in complete combustion
What is crude oil
Mixture of hydrocarbons
Where do long chain hydrocarbons go in fractional distillation
Bottom due to having high boiling points
Where do the very short chain hydrocarbons go in fractional distillation
Through the top as gas
What is feedstock
Chemical that is used to make other chemicals
Types of Feedstock
Solvents
Lubricants
Detergents
Polymers
How to test for alkenes
Alkene and bromine water goes orange to colourless
Ethane Formula
C2H4
Propane Formula
C.3H.6
Butane Formula
C.4H.8
Pentane Formula
C.5H.10
Why are alkenes unsaturated
Alkenes have 2 less hydrogens than an alkane with the same number of carbons
What makes alkenes reactive
Carbon double bond turning into single bond and bonding with other atoms
Complete Combustion equation
Hydrocarbon + Oxygen -> Carbon Dioxide + Water
Incomplete Combustion equation
Alkene + Oxygen -> Carbon + Carbon Monoxide + Carbon Dioxide + Water
