Wurtz reaction is not preferred for the preparation of alkanes containing an odd number of carbon atoms because:

1. Boiling points of alkanes obtained in the mixture are very close.
2. Melting points of alkanes obtained in the mixture are very close.
3. Lattice energy of alkanes obtained in the mixture are very close.
4. None of the above.
