Which is not an anasthetic agent in surgical operations? A. Chloroform B. Ether C. Nitrous oxide D. Acetone

The correct answer is D. Acetone.

Chloroform, ether, and nitrous oxide are all commonly used anesthetic agents in surgical operations. Acetone, on the other hand, is not an anesthetic agent. It is a flammable, colorless liquid that is used as a solvent and a fuel. It is also found in some nail polish removers and other household products.

Chloroform was first

used as an anesthetic in the early 1800s. It is a potent anesthetic that can cause respiratory arrest and death if used in high doses. Ether was also first used as an anesthetic in the early 1800s. It is a less potent anesthetic than chloroform, but it can still cause respiratory arrest and death if used in high doses. Nitrous oxide, also known as laughing gas, is a relatively safe anesthetic that is often used in dental procedures. It is a gas that is inhaled and produces a feeling of euphoria and lightheadedness.

Acetone is not an anesthetic agent because it does not have the ability to block pain or consciousness. It is a solvent that can be used to dissolve other substances, but it does not have any anesthetic properties.
