2A3 Nomen, Isom & Alkanes

Question 1

Define molecular formula

Answer 1

Actual number of each type of atom in one molecule of a compound

Question 2

Define homologous series

Answer 2

Group of compounds witch can be presented by a general formula and whose properties show gradual change

Question 3

What is structural isomers?

Answer 3

Same molecular formula but different structural formulae

Question 4

Ketone equ

Answer 4

COC

Question 5

Thermal cracking

Answer 5

Alkanes are broke using high pressure and heat

Tends to produce a lot of alkenes with shorter alkanes

Temp between 400 to 900 degrees Celsius

As temp inc, more breaks at end so shorter alkanes

To not completely break them down, time is important

Question 6

Catalytical cracking

Answer 6

ZEOLITE catalyst is used

Higher temperature around 720K

Slight pressure 100 to 500 KPa

Used mainly to produce motor fuels and aromatic and cycloalkane

Question 7

3 steps in chlorination and condition

Answer 7

Initiation

Propagation

Termination

High temp around 400 degrees celcius or UV light
