organic chemistry
fractional distillation
-
-
the bottom is hottest, coolest at the top
-
-
at the top, short chains, low b.p and low viscosity or gases
-
cracking
-
-
alkenes = double bond of carbon c=c, creates bromine water (orange/brown) positive result makes it clear
two types of cracking methods = steam cracking 850.c and steam as well as catalytic cracking uses a catalyst lowers the activation energy which happens at 550.c
crude oil
finite, non renwable and limited amount
-
methane = CH4, ethane = C2H6. propane = C3H8, butane = C4H10
