The alkane is 2-methylbutane.

The general formulas are #"R-X" + "Mg" stackrelcolor (blue)("dry ether")(→) underbrace("R-MgX")_("Grignard Reagent")# #"R-MgX" + "H"_2"O" stackrelcolor (blue)("H"^+, " H"_2"O")(→) "RH"# Your calculations are #("CH"_3)_2"CHCH(CH"_3")-Br" + "Mg" stackrelcolor (blue)("dry ether")(→) ("CH"_3)_2"CHCH(CH"_3")-MgBr"# #("CH"_3)_2"CHCH(CH"_3")-MgBr" stackrelcolor (blue)("H"^+, "H"_2"O")(→) underbrace(("CH"_3)_2"CHCH"_2CH_3)_("2-methylbutane") #

undefined The equation for the preparation of a Grignard reagent using 2-bromo-3-methylbutane is:

$$ \text{2-bromo-3-methylbutane} + \text{Mg} \rightarrow \text{Grignard reagent} + \text{MgBr}_2 $$

The alkane produced after its hydrolysis is:

$$ \text{3-methylpentane} $$
