Question

Write the equation for the preparation of a Grignard reagent using 2-bromo-3-methylbutane and name the alkane produced after its hydrolysis?

Answer 1

The alkane is 2-methylbutane.

Explanation:

The general equations 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 equations 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")`
