Question

The reaction, $C{H}_{3}C{H}_{2}Cl\underset{(ii)CuI}{\overset{(i)Li}{\to }}\stackrel{C{H}_{3}C{H}_{2}Cl}{\to }$ n-butane is known as

• A. Wurtz synthesis
• B. Corey-House synthesis
• C. Kolbe synthesis
• D. Friedel-Crafts synthesis

Answer 1

Answer: (B)

The reaction in which first, an alkyl halide reacts with lithium and $CuI$ to give lithium dialkyl cuprate which on further reaction with alkyl halide, gives alkane, is known as Corey-House synthesis. $C{H}_{3}C{H}_{2}Cl\underset{-LiCl}{\overset{Li}{\to }}C{H}_{3}C{H}_{2}Li\stackrel{CuI}{\to }$ ${(C{H}_{3}C{H}_2)}_{2}CuLi$ $\stackrel{C{H}_{3}C{H}_{2}Cl}{\to }\underset{n-bu\tan e}{C{H}_{3}C{H}_{2}C{H}_{2}C{H}_3}+C{H}_{3}C{H}_{2}Cu+LiCl$
