B. Should a high or low pressure be used?
c. Should the HCl gas be allowed to escape into another container?
3. Elemental bromine is a reddish-brown liquid. Hydrocarbon compounds that contain bromine are
colorless. A qualitative test for carbon-carbon multiple bonds is the addition of a few drops of
bromine solution to a hydrocarbon sample at room temperature and in the absence of sunlight. The
bromine will either quickly lose its color or remain reddish brown.
a. If the sample is unsaturated, what type of reaction should occur
when the bromine is added under the conditions mentioned above?
b. If the sample is saturated, what type of reaction should occur when
the bromine is added under the conditions mentioned above?
c. The reddish brown color of a bromine solution added to a
hydrocarbon sample at room temperature and in the absence of
unugnt quickly disappears. Is the sample a saturated or unsaturated
hydrocarbon?
