Answer 0

Splitting weak vdw between molecules

Question 1

Petroleum fraction

Answer 1

Mixture of hydrocarbons with a similar chain length and boiling point range

Question 2

Vacuum distillation

Answer 2

Lowers pressure over liqud which lowers it’s boiling point

Question 3

Cracking

Answer 3

A chemical process that involved splitting strong covalent bonds to split up hydrocarbon molecules

Question 4

Thermal cracking

Answer 4

High pressure and temperature, mainly alkenes, bonds broken anywhere

Question 5

Catalytic cracking

Answer 5

Low pressure, high temperature, zeolite catalyst, cheaper
