React 2,2-dibromobutane with 2 NaNH2 to to do the elimination and then add water at your final step to convert the NaCCCH2CH3 into HCCCH2CH3.

Hey dear,
● Answer -
1-butyne on bromination with Br2/H2O2 gives 1,2-dibromobutane.
● Explaination -
When 1-butyne is treated with bromine water, 1,2-dibromobutane is formed.
CH3-CH2-CH=CH2 + Br2 --> CH3-CH2-CH(Br)-CH2-Br
The reaction is called bromination. Two bromine atoms get added to carbons with double bonds. H2O2 is used as catalyst in this reaction.
Hope this helps you. Thanks for asking question, dear.
