trevor watches as a freight train passes. he counts eight identical black railroad cars, then a red car, followed by several more black cars. which type of organic compound does the train most closely model? an alkyl halide an aldehyde an ether a carboxylic acid

Answer

Answer:

D. a carboxylic acid

Brief Explanation:

In a carboxylic - acid structure, there is a long hydrocarbon chain (like the identical black railroad cars representing carbon - hydrogen groups) and a functional group (the red car representing the carboxyl group, -COOH). The structure of a carboxylic acid has a chain of carbon atoms with a distinct functional group at one end, similar to the train with a long chain of similar cars and a distinct car.
