alkene
c=c ethene
are alkene nucleophiles?
yes . double bond attacks
alkyne
c triple bond ethyne
are alkyne nucleophiles are electrophiles?
nucleophiles
are alkynes better nucleophiles?
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.”
