Question

this passage describes a chemical reaction. read the passage. then, answer the question below.

insect bites are often annoying, and bites from some types of mosquitos and ticks can cause serious health problems. to avoid being bitten, people often use insect repellents. most insect repellents contain a substance called deet (c₁₂h₁₇no), which is made by combining meta-toluic acid (c₈h₈o₂) and diethylamine (c₄h₁₁n). deet is a useful ingredient in insect repellents because insects dislike its smell.

in the chemical reaction described in the passage, which of the following are products? select all that apply.

diethylamine (c₄h₁₁n)
meta-toluic acid (c₈h₈o₂)
deet (c₁₂h₁₇no)

Explanation:

In a chemical reaction, reactants are the substances that combine to form products. The passage states that DEET ($\ce{C_{12}H_{17}NO}$) is made by combining meta - toluic acid ($\ce{C_{8}H_{8}O_{2}}$) and diethylamine ($\ce{C_{4}H_{11}N}$). So meta - toluic acid and diethylamine are reactants, and DEET is the product. The initial selections of diethylamine and meta - toluic acid as products are incorrect. Only DEET is the product here.

Answer:

DEET ($\ce{C_{12}H_{17}NO}$)
