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

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
