I need help classifying reactions for the reactions below. The possible classes are: Acid/Base reaction, Nucleophilic addition, Nucleophilic substitution, Oxidation-Reduction(Redox), Elimination, Free Radical Substitution, and Electrophilic Addition. You can only use one class for each reaction, but redox and another class is possible. Please check to see if these are correct. This is very important!!

1. Alkene ----> Alkyl Halide (Electrophilic Addition)

2. Alkyl Halide -----> Alkene (Elimination)

3. Alcohol ------> Alkene (Elimination)

4. Alkyl Halide -----> Alcohol (Nucleophilic Substitution)

5. Alkoxide -----> Alcohol (Acid/Base)

6. Aldehyde ----> Alcohol (Nucleophilic Addition)

7. Epoxide -----> Diol (Acid/Base, Redox)

8. Alkene -----> Diol (Electrophilic Addition)

9. Alkene ----> Aldehyde (Redox, Acid/Base)

10. Alcohol -----> Ketone (Elimination)

11. Alkyne -----> Ketone (Electrophilic Addition)

12. Alkene ------> Alkyl Dihalide (Redox)

13. Alkyne -----> Alkyl Tetrahalide (Electrophilic Addition)

14. Alcohol ------> Ether (Acid/Base)

15. Alkoxide -----> Ether (Redox)

16. Alkene -------> Ether (Electrophilic Addition)

17. Alkene/Alkyne ------> Alkane (Electrophilic Addition)

18. Grignard reagent ------> Alkane (Redox)

19. Alkene ----> Epoxide (Electrophilic Addition)

20. Alkene -----> Halohydrin (Electrophilic Addition, Redox)

21. Alkene -----> Allyl Halide (Acid/Base)

Why doesn't anyone know this?

it is not easy to classify them. some transformation can be done using
different methods. for example, aldehyde to alcohol, a nucleophilic addition
will work. a reduction by H2 will also work.
   besides, alcohol to ketone is an oxidation
