Answer 1

Answer :

The given chemical reation is used for prepartion of alkanes from haloalkanes$.$

Name of this chemical reaction is Corey-House synthesis.

◈ Common reation :

Step-1 :

$\sf{R-X+2Li\:\rightarrow\:R-Li+LiX}$

Step-2 :

$\sf{2R-Li+CuI\:\rightarrow\:R_2CuLi+LiI}$

Step-3 :

$\sf{R_2CuLi+R'X\:\rightarrow\:R-R'+R-Cu+LiX}$

Let's come to the question! :D

Step-1 :

$\sf{(CH_3)_3C-Br+2Li\:\rightarrow\:(CH_3)_3C-Li+LiBr}$

Step-2 :

$\sf{2(CH_3)_3C-Li+CuI\:\rightarrow\:[(CH_3)_3C)_2CuLi+LiI}$

Step-3 :

$\bf{(CH_3)_3C)_2CuLi+CH_3-(CH_2)_2-Br\:\rightarrow\:\purple{CH_3(CH_2)_2C(CH_3)_3}+CH_3(CH_2)_2Cu+LiBr}$

Final answer : CH₃(CH₂)₂C(CH₃)₃
