Question 4

alkyne

Answer 4

c triple bond ethyne

Question 5

are alkyne nucleophiles are electrophiles?

Answer 5

nucleophiles

Question 6

are alkynes better nucleophiles?

Answer 6

When a proton adds to an alkene, an alkyl cation is formed.

When a proton adds to an alkyne, a vinylic cation is formed.

A vinylic cation has a positive charge on a vinylic carbon.

It is less stable than a similarly substituted alkyl cation because the positive charge is on an sp carbon, which is more electronegative than an sp 2 carbon of an alkyl cation. This makes it less able to bear a positive charge.”
