You can revisit questions later in your account.

Give the major organic product(s) of each of the following reactions:
 

Give the name and the degree of unsaturation of the following molecules:
 

When 3,4-dimethyl-2,4-hexadiene reacts with one equivalent of HBr, 2 products are formed.

1) Draw the 1,2-addition product and the mechanism for its formation.
2) Draw the 1,4-addition product and the mechanism for its formation.
3) Which of these products is the kinetic and which is the thermodynamic?
How to promote the formation of the thermodynamic product?

 

 

3) 

Kinetic Product:
Product from the fastest reaction (best intermediate - most substituted carbocation)

Thermodynamic Product:
Most stable product (most substituted alkene). Favored by high temperature and long time

 

Show the mechanism and product of the following reaction:
 

Draw the structure of A, B, C, D and E. Add the missing synthetic condition.
