An organic compound A in reaction with Na/diethyl ether gives a hydrocarbon which on monochlorination gives only one chloro derivative. A is:
1. t-butyl chloride
2. sec. butyl chloride
3. Iso butyl chloride
4. n-butyl chloride
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. |
