This video tutorial explores alkane reactions, focusing on their low reactivity due to nonpolarity. It covers two main reactions: combustion, where alkanes react with oxygen to form CO2 and water, and radical catalyzed halogenation, where alkanes undergo substitution with halogens like chlorine or bromine under UV light. The video explains the step-by-step process of these reactions, including balancing chemical equations and the transformation of methane to carbon tetrachloride.

What is the main reason alkanes are considered non-reactive?

• They have pi bonds.

• They contain electronegative elements.

• They are nonpolar hydrocarbons.

• They have strong ionic bonds.

What is the primary intermolecular force in alkanes?

• Ionic bonding

• Hydrogen bonding

• Dipole-dipole interactions

• London dispersion forces

What is produced when an alkane undergoes combustion?

• Carbon dioxide and water

• Methane and oxygen

• Chlorine and bromine

• Hydrogen and nitrogen

Which of the following is NOT a product of alkane combustion?

• Carbon dioxide

• Water

• Methane

• Oxygen

In radical catalyzed halogenation, what is used to initiate the reaction?

• UV light

• Visible light

• Microwave radiation

• Infrared light

What happens to an alkane during radical catalyzed halogenation?

• A hydrogen is replaced with a halogen.

• A double bond is formed.

• An oxygen is added to the compound.

• A carbon is replaced with a nitrogen.

Which halogens are typically used in radical catalyzed halogenation?

• Fluorine and iodine

• Chlorine and bromine

• Oxygen and nitrogen

• Sulfur and phosphorus

What is the final product when methane undergoes complete radical catalyzed halogenation with chlorine?

• Methylene chloride

• Carbon tetrachloride

• Methane chloride

• Chloroform

What is the main difference between combustion and radical catalyzed halogenation of alkanes?

• Combustion involves oxygen, while halogenation involves halogens.

• Combustion is an organic reaction, while halogenation is not.

• Combustion produces halogens, while halogenation produces water.

• Combustion requires UV light, while halogenation does not.

Which of the following is a characteristic of the radical catalyzed halogenation reaction?

• It involves the addition of oxygen.

• It is a type of combustion reaction.

• It can replace multiple hydrogens with halogens.

• It is a non-polar reaction.
