Understanding Hydrocarbons and Bromine Reaction

The video tutorial explains the difference between saturated and unsaturated hydrocarbons using cyclohexane and cyclohexene. Bromine is added to both substances. In cyclohexane, a saturated hydrocarbon, bromine dissolves without reacting, maintaining its color. In cyclohexene, an unsaturated hydrocarbon, bromine reacts and the color disappears, indicating the presence of a double bond. This reaction serves as a test for unsaturation in hydrocarbons.

What type of hydrocarbon is cyclohexane?

• Unsaturated

• Saturated

• Aromatic

• Aliphatic

Why does the color remain when bromine is added to cyclohexane?

• Bromine changes color upon stirring

• Bromine evaporates quickly

• Bromine reacts with cyclohexane

• Bromine does not react with saturated hydrocarbons

What happens when bromine is added to cyclohexene?

• The solution remains unchanged

• The solution turns blue

• The solution becomes more viscous

• The red-brown color disappears

What is the significance of the bromine test with cyclohexene?

• It shows the absence of any bonds

• It confirms the presence of a triple bond

• It tests for aromaticity

• It indicates the presence of a double bond

Which hydrocarbon reacts with bromine to indicate unsaturation?

• Ethane

• Cyclohexene

• Methane

• Cyclohexane
