Reaction between propyne and sodium amide and the effect of the solvent

Please help me on following question. :'(

You are planning to carry out a reaction between propyne, CH3C?CH and sodium amide, NaNH2.  You also need to choose an appropriate solvent for carrying out the reaction.  Would ethanol be suitable for this purpose?  Explain your rationale clearly.

 

H-C?C-H  +  NaNH2  (in ammonia or ether)  ——>  H-C?C-Na (sodium acetylide)  +  NH3

The reaction appears to depend on the acidity of the alkyne which is why ammonia or ether are weaker acids than the alkyne.  I believe that alcohol would not work because of the possibility of it acting as an acid.
