Carbocation Fundamentals (Stability, Rearrangement, SN1)

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 # 334

 Let's go over how a carbocation can form from an alkene.

Use curved arrows to show the two carbocations that can from from 1-methylcyclohexene.

 

Problem # 333

Let's go over how a carbocation can form from an alcohol.

Write in the curved arrows to show the formation of the protonated alcohol, and water acting as a leaving group to form a carbocation.

Problem # 332

Each of the carbocations below will spontaneously rearrange. Draw the structure of the expected rearrangement product.

Problem # 331

Rank the carbocations below in order of decreasing stability. (1 = most stable)

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.
