Question 1 of 27070

You have a tow of chemical barges. The mate reports an ammonia smell around the head of the tow. You would suspect a leak in the barge carrying which substance?

🔍 Key Concepts

• Relationship between chemical odor and the substance’s functional group (for example, amines vs hydrocarbons vs chlorinated solvents) • Typical odors of amines compared to hydrocarbons and chlorinated compounds • How an "ammonia smell" is often used as a clue to identify amine-type cargoes in tank and barge questions

💭 Think About

• First, separate the choices into likely amine-type chemicals and those that are not amines based on their names and endings (e.g., -amine). • Think about which types of cargoes are known for having ammonia or fishy odors versus gasoline-like odors or sweet/chloroform-like odors. • Ask yourself: if the smell is specifically described as ammonia, which chemical family in the list most closely mimics or relates to ammonia’s structure and odor?

✅ Before You Answer

• Identify which of the choices are amines (look for the -amine ending and nitrogen-containing names). • Eliminate any choice that is a clear hydrocarbon (pure fuel-type substance) or a chlorinated solvent, since these typically do not smell like ammonia. • From the remaining candidates, pick the one most commonly associated with an ammonia-like or amine-like odor in cargo-handling references.
