Question

 

1. What are the 10 common elementary steps in chemical reactions and why is important to know these elementary steps in organic chemistry?

2.For each elementary step, give an example of that step that happens in a chemical reaction? (Please show all work)

Answer 1

1,)

10 elementary steps are

1) Nuclephilic substitution (SN1 and SN2)

2) Co-ordination

3) Heterolysis

4) Elimination (unimolecular,E1 and bimolecular, E2)

5) Nucleophilic addition

6) Nucleophilic elimination

7) Electrophilic addition

8) Electrophilic elimination

9) Carbocation rearrangement

10) Proton transfer reaction

All these reactions foundation steps for many organic reactions. Identifying the suitable elementary step for achemical reaction will lead us to attain desired product.

2)

1) Nuclephilic substitution (SN1 and SN2)

in this reaction an atom or group is relplaced by another atom or group
