properties of hydrocarbons

Question 1

what are the first 4 hydrocarbons

Answer 1

C1 methane
C2 ethane
C3 propane
C4 butane

Question 2

what does viscosity tell us?

Answer 2

the thickness of a fluid

Question 3

fluids with a ___ viscosity flow slowly

Answer 3

high

eg honey

Question 4

what happens as the size of the hydrocarbon molecules increases?
this means…

Answer 4

the molecules get more viscous
very long chain hydrocarbons flow very slowly and are extremely viscous

the molecules get less flammable, long chain hydrocarbons are very difficult to burn

Question 5

what does flammability tell us about a hydrocarbon

Answer 5

Flammability tells us how easily a hydrocarbon combust in other words burns

Question 6

_____ chain hydrocarbons are extremely flammable

Answer 6

short chain

Question 7

____ hydrocarbons are very difficult to burn

Answer 7

long chain

Question 8

what is a boiling point

Answer 8

the temperature at which a liquid turns to a gas

Question 9

_____ chain hydrocarbons have low boiling points

Answer 9

short chain

Question 10

all first 4 hydrocarbons are liquid/solid/gas at room temperature ?

Answer 10

gas

because they all have boiling points which are lower than their temperature

Question 11

very long chain hydrocarbons have very what boiling points

Answer 11

high
