Which inhalant is the most potent with slow recovery and tissue retention?

Explanation:
The key idea is how soluble an inhalant anesthetic is in blood and body tissues. The more soluble it is, the more it is taken up during anesthesia and the more it lingers in tissues after the gas is stopped, leading to slower recovery as it gradually washes out. Methoxyflurane has extremely high solubility in both blood and lipids, making it very potent but also causing it to stay in tissues longer and wash out slowly. That combination—high potency with slow emergence and tissue retention—fits methoxyflurane best. The other agents have lower solubility, so they wash out more quickly, resulting in faster recovery.
