Question

# Which of the following are alicyclic compounds?a.) Cyclopropaneb.) Ethanec.) Benzened.) Pyridine

Cyclopropane, also known as trim ethylene, toxic, colorless gas which has been used as a general anesthetic in medicine since 1934. Cyclopropane does not irritate mucous membranes and does not inhibit breathing. Rapid and smooth induction and emergence from cyclopropane anesthesia is typically. Inhalation is used to deliver a mixture of around 5 to 20 per cent cyclopropane in oxygen. It is typically used in a closed (rebreathing) system because of the flammability and cost of cyclopropane, in which an absorbent chemical such as soda lime absorbs exhaled carbon dioxide and the anesthetic is recirculated. The molecular formula for this is ${C_3}{H_6}$.
