Question

Explain the wurtz reaction is not very useful when two different alkyl halides are used

Answer 1

heya........


If two different alkyl halides are used in Wurtz reaction to prepare an alkane with odd number of carbon atoms, a mixture of three alkanes is actually produced. ... The boiling point of these alkanes are very close as molecular mass is almost same and hence they cannot be separated by fractional distillation

Answer 2

Hey mate!

Here's your answer!!

If two different alkyl halides are used in Wurtz reaction to prepare an alkane with odd number of carbon atoms, a mixture of three alkanes is actually produced, this is due to the reason that the two alkyli halides in addition to reacting with each other also react among themselves giving a mixture of three alkanes.

For example consider iodomethane (CH3-I) and iodoethane (CH3-CH2-I) and you want to prepare propane by Wurtz reaction then these reactions will take place (shown in the given attachment).
