Organic Chemistry - Alkanes

Question 1

what is the general formula for alkanes?

Answer 1

alkanes have the general formula CₙH₂ₙ₊₂

Question 2

what is a saturated hydrocarbon?

Answer 2

a molecule containing only single bonds between carbon atoms

Question 3

what is an unsaturated hydrocarbon?

Answer 3

a molecule containing a carbon-carbon double or triple bond

Question 4

what type of hydrocarbon are alkanes?

Answer 4

saturated

Question 5

what is the reaction between alkanes and halogens?

Answer 5

• alkanes react with bromine in the presence of UV light
• a hydrogen atom in the alkane is replaced by a bromine atom, so this is a substitution reaction
