"R"_1-"C"-="C"-"R"_2R1CCR2, I suppose, since this is an alkyne, a hydrocarbon with a triple bond (and a pure alkyne has no double bond).

From the single "H"H on the far right, the far-right carbon must be spsp-hybridized. It has two sigmaσ bonds, one with that right-hand "H"H and one with the next to last carbon.

Structurally...

"H"_3"C"-"CH"_2-"C"-="C"-"H"H3CCH2CCH

Can you rationalize why this compound is called 1-butyne?
