							since 1butyne is a terminal alkyene therefore itbwill shpw the test of terminal alkyene whereas 1 butene will not show.
the basic of this difference is the acidic character of terminal alkyene.
reaction:-
(1)CH3CH2CCH + AgNO3----CH3CH2CCAg(white ppt) +NH4NO3 + H2O
(2)2CH3CH2CCH +Cu2CL2 +2NH4OH----2CH3Ch2CCu(red ppt) + 2NH4Cl + 2H2O

1 butene do not show this test

thanks and regards
