JEE MAIN - Chemistry (2005 - No. 50)
Alkyl halides react with dialkyl copper reagents to give
alkenes
alkyl copper halides
alkanes
alkenyl halides
Explication
In Corey House synthesis of alkanes alkyl halide react with lithium dialkyl cuprate
$$R'X + Li{R_2}Cu\buildrel \, \over \longrightarrow R' - R + RCu + LiX$$
$$R'X + Li{R_2}Cu\buildrel \, \over \longrightarrow R' - R + RCu + LiX$$
