Question
A mixture of 1-iodoethane and 1-iodopropane is treated with sodium metal and dry ether to carry out Wurtz reaction. Which of the following hydrocarbons will be formed?
A.
Propane + Hexane
B.
Ethane + Propane
C.
Butane + Propane
D.
Butane + Pentane + Hexane
Answer :
Butane + Pentane + Hexane
Solution :
$$C{H_3}C{H_2}I + 2Na + IC{H_2}C{H_2}C{H_3}$$ \[\xrightarrow{\text{ether}}\underset{\text{Butane}}{\mathop{C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}C{{H}_{3}}}}\,\,\,+\] \[\underset{\text{ Pentane}}{\mathop{C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}C{{H}_{2}}C{{H}_{3}}}}\,\,\,+\] \[\underset{\text{Hexane}}{\mathop{C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}C{{H}_{2}}C{{H}_{2}}C{{H}_{3}}}}\,\]
