Double elimination of 1,2-haloalkane with 2 equivalents sodamide gives the alkyne.
Sodamide undergoes acid-base reaction with alkyne to form alkynide species which react with methyl iodide in SN2 fashion to form the product.
Hydrogenation of alkyne with excess hydrogen in presence of platinum catalyst yields the alkane.
Hydration of alkyne in presence of H2SO4 and HgSO4 yields the ketone.
Alkene undergoes cyclopropanation on reaction with Simmons-Smith reagent.
Ozonolysis with dimethyl sulfide work up forms the aldehyde.
