definition of carbon compound
a compound that consists of carbon atom as their constituent element
definition, sources of organic compound
originating from living things
living things, decomposed organism
definition, sources of inorganic compound
originating from non living things
minerals in the soil
give 4 examples of organic compound
fats: coconut oil
protein: mil
carbohydrate
petroleum
organic compounds are divided into 2. name them
hydrocarbon
non hydrocarbon
hydrocarbon are divided into 2. name them
saturated
unsaturated
what are saturated hydrocarbons?
contain only single bonds between carbon atoms
what are unsaturated hydrocarbons?
contain at least one double/triple bond between carbon atoms
what is the source of hydrocarbon
petroleum/crude oil
what are the 2 stages in oil refining
fractional distillation
cracking
definition of fractional distillation
fractions of hydrocarbon in petroleum are separated at different temp according to size of hydrocarbons
at the top of fractionating column, what is the boiling point, when does it vaporise, colour, combustibility and viscosity?
low boiling point vaporise first then rise up and condense bright colour highly combustible less viscous
at the bottom of fractionating column, what is the boiling point, colour, combustibility and viscosity?
high boiling collected and condense into liquid dark colour low combustibility more viscous
