What is the name of the product formed by the reaction of propylide ion and 2-chloropropane? I'm having problem because I don't know the formula of propylide ion.

the name of the product is 4 methyl 2 pentyne. a propylide ion is a three carbon structure with a triple bond between the second and third carbons and a negative charge on the last carbon. the first carbon is bonded to three hydrogens. CH3CC-

Nope, Kristen is right. It can also be written as 4-methylpent-2-yne but it's the same thing.

also written as 4-methyl-2-pentyne

4-methyl-pent-2-yne

4-methylpent-2-yne ...is correct

thanks for the answer :)

Amanda is correct

So what happens to the "chloro" part?

The chlorine takes the electrons from it's bond and leaves with a full valence and a negative charge.

Draw the structure for the product of the reaction between 2-butene and hydroiodic acid, HI.
