Questions
  1. Items
    1. Ethene
    2. Methane
    3. Ethane
    4. Propane
    Reason
    Ethene has a double bond, so it is an alkene. The other three are saturated alkanes.
    Odd item
    Ethene
  2. Items
    1. Alkanes
    2. Alcohols
    3. Alkenes
    4. Alkynes
    Reason
    Alcohols contain oxygen. The other three are hydrocarbon families made of carbon and hydrogen only.
    Odd item
    Alcohols
  3. Items
    1. CnH2n+2
    2. CnH2n
    3. CnH2n+1OH
    4. CnH2n-2
    Reason
    CnH2n+1OH is the alcohol formula. The other three are the alkane, alkene and alkyne general formulas.
    Odd item
    CnH2n+1OH
Instructions
Tap the item that does not belong with the rest.
