    • Amines are structurally similar to ammonia but have hydrogen atoms replaced by alkyl or aryl groups.

      True
    • What type of substituents are found in amines?
      Alkyl or aryl groups
    • The number of substituents on the nitrogen atom in amines affects their chemical properties.

      True
    • Match the type of amine with its definition:
      Primary Amine ↔️ One alkyl or aryl group attached to nitrogen
      Secondary Amine ↔️ Two alkyl or aryl groups attached to nitrogen
      Tertiary Amine ↔️ Three alkyl or aryl groups attached to nitrogen
    • What is an example of a secondary amine according to its nomenclature?
      Dimethylamine
    • Steps to name the tertiary amine `(CH3)3-N`
      1️⃣ Identify it as a tertiary amine
      2️⃣ Name the three methyl groups
      3️⃣ Add "amine" to the end
      4️⃣ The name is Trimethylamine
    • Boiling points of amines are higher than alkanes but lower than alcohols.

      True
    • Match the amine type with its naming convention:
      Primary Amine ↔️ Name the alkyl group followed by "amine"
      Secondary Amine ↔️ Name the two alkyl groups prefixed by "N-" followed by "amine"
      Tertiary Amine ↔️ Name the three alkyl groups prefixed by "N-" followed by "amine"
    • Amines are soluble in water if they have small alkyl groups
      True
    • Most amines have a characteristic ammonia-like odor
    • The lone pair of electrons on the nitrogen atom makes amines nucleophilic, allowing them to participate in substitution reactions
    • Many drugs contain amine groups for their biological activity
    • Order the applications of amines based on their primary benefits:
      1️⃣ Pharmaceuticals for biological activity
      2️⃣ Dyes for vibrant colors
      3️⃣ Cosmetics for stability and color
      4️⃣ Plastics for strength and durability
      5️⃣ Agricultural Chemicals for crop protection
    • What is the key structural feature of amines?
      Nitrogen atom with lone pair
    • The general formula for a primary amine is R-NH2
    • A primary amine has one alkyl or aryl group attached to the nitrogen
    • What is an example of a primary amine?
      Methylamine
    • The naming convention for primary amines involves naming the alkyl or aryl group followed by the word amine
    • To name a tertiary amine, you name all three alkyl or aryl groups and add "amine" at the end.

      True
    • What is the characteristic odor of most amines?
      Ammonia-like
    • Amines are soluble in water if they have small alkyl groups.
    • The nitrogen atom in an amine has a lone pair of electrons
    • Amines are classified based on the number of alkyl or aryl groups attached to the nitrogen atom

      True
    • The number of substituents in an amine affects its reactivity and physical properties

      True
    • For mixed substituents in naming amines, they should be listed alphabetically
    • The boiling points of amines are higher than alkanes but lower than alcohols
    • Amines are basic compounds due to the lone pair of electrons on the nitrogen atom

      True
    • Match the property of amines with its explanation:
      Basicity ↔️ Lone pair of electrons on nitrogen
      Nucleophilicity ↔️ Lone pair allows substitution reactions
      Reactivity with Acids ↔️ Forms ammonium salts
    • Amines are used in cosmetics to add stability and color

      True
