Organic Chemistry Flashcards
What is the general formula for alkanes?
CₙH₂ₙ₊₂
Are alkanes saturated or unsaturated hydrocarbons?
Saturated
Are alkenes saturated or unsaturated hydrocarbons?
Unsaturated
What happens to the boiling point as hydrocarbons get larger?
Boiling point increases (volitility decreases)
What happens to the flammability as hydrocarbons get larger?
Flammability decreases
What happens to the flame as fractions get larger?
It becomes smokier
What happens to the viscosity as fractions get larger?
Viscosity increases
How is crude oil separated?
Fractional distilation.
What are the 2 types of cracking?
- Catalytic cracking
- Steam cracking
What is produced by cracking?
Shorter chain alkanes and alkenes
What is a double bond?
Where 2 pairs of electrons are shared between atoms.
What type of reaction is used in cracking?
Thermal decomposition reaction.
What is the test for unsaturated hydrocarbons?
Bromine water
Turns from orange to colourles.
What is the general formula for alkenes?
CₙH₂ₙ
