Which gas is known to smell like garlic?

• A. Acetylene
• B. Propane
• C. Butane
• D. Hydrogen

Answer: (A)

Acetylene is known to have a distinctive odor reminiscent of garlic. This characteristic scent is due to the compounds present in acetylene and is particularly useful for safety purposes. The odor helps in the early detection of gas leaks, allowing individuals to take action before the concentration becomes hazardous. In the context of fuel gases typically encountered, acetylene is a widely used fuel in welding and cutting applications and its garlic-like smell is a critical feature that aids in maintaining safety in environments where it is present. The other gases listed, while also being used in various industrial and commercial applications, do not have a similar characteristic odor that could be used as an identifying feature for safety.
