The product is 2-methylbutane.

Explanation:

Hydrogen adds to alkenes in the presence of catalysts like "Pt", "Pd", and "Ni".

The equation for the hydrogenation of 2-methylbut-2-ene is

underbrace(("CH"_3)_2"C=CHCH"_3)_color(red)("2-methylbut-2-ene") + "H"_2 stackrelcolor (blue)("Pt, Pd, or Ni")(→) underbrace(("CH"_3)_2"CH-CH"_2"CH"_3)_color(red)("2-methylbutane")

The product has a chain of four carbon atoms with a methyl group on "C-2", hence the name 2-methylbutane.
