Final answer:
c) Inhalation anesthetics
Anesthetics ending in -ane are inhalation anesthetics used to induce and maintain unconsciousness during surgery. They are halogenated ethers and are part of modern volatile anesthetic compounds used in anesthesia machines.
Step-by-step explanation:
The anesthetics that end in -ane, such as halothane, enflurane, and isoflurane, are inhalation anesthetics. These modern, inhalant, halogen-containing compounds are less flammable than diethyl ether and are used to induce and maintain a state of unconsciousness during surgical procedures.
Enflurane, for example, is one of the several volatile anesthetics that have been used for this purpose. In contrast, injection anesthetics like propofol and barbiturates are administered intravenously and are known for their quick and reliable induction of anesthesia.
