As we know that terminal Alkyne (alkyne with triple bond at the end) are acidic in nature, they can donate proton. When Sodium Hydride is reacted with 1-Octyne, the hydride abstract the terminal proton and forms Hydrogen Gas, while Methyl Magnesium Bromide when reacted with 1-Octyne eliminates Methane gas. Both reactions are given below,

Result:

Gas evolved in reaction of NaH is H₂.

Gas evolved in reaction of CH₃MgBr is CH₄.
