EXPERIMENT 8 TEST

Question 1

what was collected in the preparation of acetylene gas? How was it collected?

Answer 1

acetylene gas was collected, though the process of water displacement

Question 2

what test was used to identify the alkene or alkane functional groups in the compount?

Answer 2

Bromine water test
Alkane has no reaction
Alkene creates the presence of MnO2 (manganese oxide)
