Understanding Short And Long Chain Molecules

Question 1

How does boiling point relate to chain size

Answer 1

Short chain molecules boil at a lower temp as chain length increases the boiling point of the hydrocarbon also increases. As it requires more energy to overcome intermolecular forces

Question 2

How does chain size relate to viscosity

Answer 2

Shorter chain length is more thin and less viscous and a longer chain is more viscous (thicker)

Question 3

How does chain size relate to how well a substance burns

Answer 3

A shorter chain length will burn better (more flammable) but longer won’t burn aswell

Question 4

How will a long hydrocarbon separate ?

Answer 4

At first it an alkane but then it will create an Alkene and alkane

Such as C11 H24 will make C8H18 and C3 H6
