Final answer:
Multiple extractions with diethyl ether are often required to completely isolate an uncharged organic solute due to the solvent's weak dipole-dipole intermolecular forces.
Step-by-step explanation:
The question pertains to solvent extraction, a common lab technique in chemistry used to isolate compounds based on their solubility in different solvents.
The statement that one extraction with diethyl ether will not completely isolate the uncharged organic solute is typically true.
This is due to the partition coefficient of the solute between the water and organic phases, which may require multiple extractions to effectively transfer a substantial amount of the compound into the ether.
Diethyl ether, which has relatively weak dipole-dipole intermolecular forces, does not create strong surface tension interactions, affecting the efficiency of the extraction process.
