What state are alkanes with chain length C5 - C16
Colourless liquids
What state are alkanes with chain length C17 +
White Waxy Solids
As chain length increases does the B.P. Increase or decrease and why
Increases * As chain length increases, molecules have a larger surface area * More surface contact is possible between molecules * London forces between molecules will be greater * More energy required to overcome them
As Branching increases does BP increase or decrease and why
Decreases * As branching increases, there are fewer surface points of contact, leading to fewer London forces * Branching increases, molecules can’t get as close together as straight chains, leading to weaker London forces * Less energy required to overcome them
In a limited, not extremely limited supply what products are formed from the combustion of alkanes
Carbon Monoxide Water
In an extremely limited supply what products are formed from the combustion of alkanes
Carbon Water
What condition is required for alkanes to react with halogens (Cl2) or Br2)
UV light or sunlight
When an alkane is reacted with a halogen what is the colour change and observed change on litmus paper
red-brown —> Colourless Litmus paper turns red
