SN1 mechanism

Problem # 572
 

Let's work through a conjugate addition problem.

Write out the mechnanism for the formation of the 1,2 and 1,4 products of the reaction below.

Problem # 542

 

Rank the following compounds in order of decreasing reactivity with water (solvolysis). (1 = most reactive)

Problem # 522

Let's work through a 1,2 and 1,4 addition. Draw the structures for each of the species in the six boxes below. Also draw curved arrows to show electron movement. 

Problem # 347

For the reaction below, draw the structures of the carbocation intermediate and the final product.

Problem # 337
 

Predict the product(s) of the reaction below, and used curved arrows to show a mechanism.

Problem # 335

Carbocations aren't very stable and so don't last very long after they are formed.

Use curved arrows to show:

a) how a carbocation reacts with a halide ions to form an alkyl halide.

b) how a carbocation reacts with water to form an alcohol.

c) how a carbocation reacts with a base to form an alkene.

Problem # 322
 

Using curved arrows, draw a mechanism for the SN1 reaction shown below.

Problem # 321
 

Using curved arrows, draw a mechanism for the SN1 reaction shown below.
