After this lesson, you should be able to:

• Describe criteria to classify reactions according to structural change
• Identify addition reactions (hydrohalogenation, halogenation, hydration, hydrogenation)
• Identify elimination reactions (dehydrohalogenation, dehydration of alcohols, cracking of hydrocarbons)
• Distinguish between primary, secondary and tertiary carbons and how they are linked to primary, secondary and tertiary alcohols
• Identify substitution reactions
