Gaseous or highly volatile liquid anesthetics are often preferred in surgical procedures because once inhaled, these vapors can quickly enter the bloodstream through the alveoli and then enter the brain. Several common gaseous anesthetics are shown with their boiling points:

Based on intermolecular force considerations, explain the advantages of using these anesthetics. (Hint:The brain barrier is made of membranes that have a nonpolar interior region.)
