Structure and Properties of Haloalkanes

Question 1

What are haloalkanes?

Answer 1

= halogen atom bonded to an alkane
= CnH2n+1X

Question 2

What is a primary haloalkane?

Answer 2

= halogen is bonded to a carbon atom that is bonded to one other carbon atom

Question 3

What is a secondary haloalkane?

Answer 3

= halogen is bonded to the carbon atom which is bonded to 2 other carbon atoms

Question 4

What is a teritary haloalkane ?

Answer 4

= halogen is bonded to the carbon atom that is bonded to 3 other carbon atoms

Question 5

What type of bond is a carbon to halogen bond (C-X)?

Answer 5

= polar
= carbon is partial positive
= halogen is partial negative

Question 6

What is the first property of haloalkanes?

Answer 6

= haloalkanes have a higher boiling point than the respective alkane
= intermolecular forces
alkanes: vanderwall forces, weak
haloalkanes: dipole dipole forces + vanderwall forces

Question 7

As we move down the group what happens to the boiling points?

Answer 7

= boiling points- vandwerwall forces, electrons increases

Question 8

What is the solubility of haloalkanes?

Answer 8

= insoluabnle
= cannot form hydrogen bonds
= not electronegatibe

=soluable on non-polar solvebts
