Which of the following reactions is not feasible?A. `(CH_(3)CH_(2))_(2)CuLi+CH_(3)CH_(2)C(CH_(3))_(2)Brrarr`B. `[(CH_(3))_(3)C]_(2)CuLi+CH_(3)CH_(2)CH_(2)Brrarr`C. `[CH_(3)CH_(2)C(CH_(3))_(2)]_(2)CuLi+CH_(3)CH_(2)Brrarr`D. `[(CH_(3))_(2)CH]_(2)CuLi+(CH_(3))_(2)CHCH_(2)Brrarr`

Answer» Correct Answer - A
Not feasible because the alkyl halide which reacts with lithium dialkycuprate must be methyl halide, primary halidie `(RCH_(2)X)` or secondary `(R_(2)CHX)` halide. Halide in the first reaction is a tertiary halide.
