1. Arrange students into groups. Each group needs at least ONE person who has a mobile device.
2. If their phone camera doesn't automatically detect and decode QR codes, ask students to
4. Cut them out and place them around your class / school.
1. Give each group a clipboard and a piece of paper so they can write down the decoded questions and their answers to them.
2. Explain to the students that the codes are hidden around the school. Each team will get ONE point for each question they correctly decode and copy down onto their sheet, and a further TWO points if they can then provide the correct answer and write this down underneath the question.
3. Away they go! The winner is the first team to return with the most correct answers in the time available. This could be within a lesson, or during a lunchbreak, or even over several days!
4. A detailed case study in how to set up a successful QR Scavenger Hunt using this tool can be found here.

1. QUESTION 1A) Draw display formula for 2,3-dimethylbutane | 1A | 2. QUESTION 1B) Draw display formula for 3-methyl-2-pentene | 1B | 3. QUESTION 2A) Thermal cracking is applied in high pressure and temperature, heterolytic fission and produces mostly alkenes. TRUE OR FALSE | 2A | 4. QUESTION 2B) catalytic cracking is applied in high pressure and temperature, heterolytic fission and produces mostly branched and cylic alkanes | 2B | 5. QUESTION 3A) How many possible chain isomerism exists for pentane? Please draw all of them? | 3A | 6. QUESTION 3B) How many isomerism exists for C4H9Cl? (Note:After solving the question, your mission is to write 5 lab rules on the sheets. Then you will get a clue from a teacher). | 3B | 7. QUESTION 4A) One of physical properties of alkanes is that the longer chain carbon exists, the lower boiling point is. TRUE OR FALSE. (Note:After solving the question, your mission is to test H2 gas from reaction of Mg ribbon and HCl. then Come to your teacher to have a clue) | 4A | 8. QUESTION 4B) Alkanes are fairly unreactive, relatively strong, almost non-polar, often to be attacked by free radicals. TRUE OR FALSE | 4B | 9. QUESTION 5A) Electrophilic addition happens when C2H4 reacts with Br2 to form a single product. Please write a chemical reaction and state the name of the product? | 5A | 10. QUESTION 5B) Direct hydration happens when alkene reacts with H2O (reagent is steam and phosphoric acid as a catalyst) to produce an alcohol. Draw hydration chemical reaction for C2H4 and state a name of alcohol product?(Note:After solving the question, your mission is to make a solution of 0.1 Molar of CuSO4.Then you will get a clue from a teacher) | 5B | 11. QUESTION 6A) Oxidation of alkenes can be done with cold dilute acidified KMnO4 that changes from colourless to pink. TRUE OR FALSE. | 6A | 12. QUESTION 6B) Markovnikov’s principle states unsymmetrical alkene so that the most stable carbocation is formed as an intermediate. The order of increasing stability is tertiary-secondary-primary-methyl. TRUE OR FALSE. (Note:After solving the question, your mission is to test the pH of liquid soap using pH paper then you will get a clue from a teacher) | 6B |
