Question

A dead fish has washed up on the beach and is starting to decay. Which compound produces the unpleasant odor from the decaying fish?

pentane-1,5-diamine
hexane-1,5-diamine
hexane-1,6-dithiol
2-pentanone

Answer 1

The correct answer is pentane-1,5-diamine

Step-by-step explanation:

The distinctive smell of dead animals comes largely from molecules like cadaverine and putrescine that are made when proteins break down, but the decomposition of high-protein plants can make a deathly smell too. Cadaverine is a foul-smelling diamine compound produced by the putrefaction of animal tissue. Cadaverine is a toxic diamine with the formula NH2(CH2)5NH2, which is similar to putrescine. It is the chemical that comes from dead fish

Answer 2

The correct option in here is the first one: pentane-1,5-diamine. This is also known as cadaverine. This is a common compund that produces that unpleasant odor from the fish.
