[KCET 2004]
Options:
A) 2-chloropropane and chloromethane
B) 2-chloropropane and chloroethane
C) Chloromethane and chloroethane
D) Chloromethane and 1-chloropropane
Show Answer
Answer:
Correct Answer: A
Solution:
It is Wurtz reaction in which hydrocarbon formed when alkyl halide react with Na metal in dry ether. $ \underset{\text{2 chloro propane}}{\mathop{CH_3-\overset{Cl\ }{\mathop{\overset{|}{\mathop{C}}H}}-CH_3}}+\underset{\begin{smallmatrix} chloro \\ methane \end{smallmatrix}}{\mathop{CH_3Cl}}+2Na\xrightarrow{ether} $
$ \underset{\text{2 methyl propane}}{\mathop{CH_3-\overset{CH_3\ }{\mathop{\overset{|}{\mathop{C}}H-}}CH_3+2NaCl}} $
