Question 2

Consider the carbocations shown below. Which carbocation is more stabilized and why?
 
  1.The vinyl cation is more stabilized due to resonance.
  2.The vinyl cation is more stabilized because it is a stronger Lewis acid.
  3.The vinyl cation is more stabilized because of hyperconjugation.
  4.The ethyl cation is more stabilized due to a C-H/p orbital interaction.
  5.The ethyl cation is more stabilized due to a C-H/p orbital interaction.

Question 3

Question 4

What is the structure of intermediate I?
 

Question 5

A reaction of propyne with Hg2+ is run in methanol (CH3OH) in the absence of water, but in the presence of a strong acid (H+) with a non-nucleophilic counterion. If this reaction follows a typical mechanism of electrophilic addition, what would be the expected product?
   

Question 6
