Compound X, a geminal dihalide, is exposed to excess strong base (excess NaNH2 then H2O) to produce an alkyne (compound Y). Alkyne Y is a terminal alkyne, has a molecular formula of C5H8, and has exactly 4 distinct resonances in the (proton-decoupled) 13C NMR spectrum. What are the two possible structures for compound X?
