Dear Student
 
1) On adding a soln of ammoniacal Na, ethyne will form HC CNa.
 
HCΞCH + Na -----> HCΞC Na
 
2)On addition of CH3Br to this, it will form propyne.
 
HCΞC Na + CH3Br -----> HCΞCCH3
 
3) Propyne on reaction withHgSO4 gives acetone.
 
H3C-C C-H (propyne) + H2O + HgSO4 + H(+) --> CH3-C(=O)-CH3 (acetone)
 
We hope that clarifies your query.
