Organic Chemistry Answers

reaction mechanism types:

• Addition e.g. aldehyde or ketone with HCN

• Substitution e.g. halogenoalkane with aqueous NaOH

• Elimination e.g. halogenoalkane with ethanolic NaOH

• Addition-elimination e.g. aldehyde or ketone with 2,4-dinitrophenylhydrazine

This section must explore and interpret the similarities and differences between each of the four mechanisms
