Organic Reactions Quiz

1. Substitution reactions: involve nucleophilic substitution, free radical substitution, and electrophilic substitution. 2) Addition reactions: involve electrophilic addition, nucleophilic addition, and free radical addition. 3) Elimination reactions: involve E1 and E2 mechanisms. 4) Oxidation-Reduction reactions. 5) Cyclization reactions. 6) Rearrangement reactions.

A chemical reaction is the transformation of one chemical or collection of chemicals into another chemical or collection of chemicals. It involves making new chemical bonds and breaking old chemical bonds.

In a nucleophilic substitution reaction, a nucleophile displaces a leaving group in the molecule or substrate that undergoes the substitution. For example, in SN1 and SN2 reactions, a nucleophile replaces a leaving group in the substrate, resulting in the formation of a new compound.

<p>Markonikoff’s rule states that in the addition of a polar molecule to an unsymmetrical alkene, the negative part of the adding molecule becomes attached to the carbon atom that has the greater number of hydrogen atoms. This rule is significant in predicting the regiochemistry of electrophilic addition reactions.</p> Signup and view all the answers

<p>Oxidation-reduction reactions involve the transfer of electrons from one species to another. Examples of oxidizing agents mentioned in the text include KMnO4 and K2Cr2O7, while examples of reducing agents include LiAlH4 and NaBH4.</p> Signup and view all the answers
