What is the major organic product of the reaction of 1 mol pent-1-yne with 1 mol of sodium amide followed by 1 mol iodoethane?

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

just did the assignment and the answer was #1 +2 n
