alkenes

Question 1

unsaturated

Answer 1

the double bond can open up and they can make more bonds

Question 2

alkanes have

Answer 2

double carbon bond

Question 3

alkenes react with

Answer 3

halogens, forming haloalkenes

Question 4

ethernet + bromine

Answer 4

=dibromoethane (no double bond and bromine is connected to carbon atoms

Question 5

what kind of reaction

Answer 5

addition reaction. because carbon double bond splits and halogen atom is added to each carbons

Question 6

test for carbon carbon double bonds

Answer 6

shake alkene with orange bromine water, solution becomes colourless, because bromine molecules which are orange, react with alkene to make dibromoalkane, which is colourless. alkanes dont react with bromine water as they don’t have a double bond. iff you add alkene to bromine water, it will stay orange
