C5 - Organic Chemistry : Crude Oil and Hydrocarbons

give 4 examples of things produced from crude oil

plastics, pharmeceuticals, petrol, cosmetics

where is crude oil found

in rocks

what is a finite resource

One that will eventually run out

is crude oil a finite resource

yes

how many years ago was crude oil formed

millions

how is crude oil formed

from the remains of tiny sea creatures

what is the tiny sea creatures called

plankton

where were planktons buried

in mud

what is crude oil a mixture of

molecules

what are these molecules called

hydrocarbons

what is methane

a hydrocarbon

what does methane contain

one carbon atom covalently bonded to four hydrogen atoms

what are hydrocarbons

Compounds that only contain carbon and hydrogen

What do scientists call hydrocarbons like methane and ethane?

alkanes

What is the general formula for alkanes?

CₙH₂ₙ₊₂ (However many carbons there are, you multiply this by 2 and add 2 to get the number of hydrogens.)

what are alkanes

saturated molecules

why are alkanes saturated molecules

Because the carbon atoms are fully bonded to hydrogen atoms
