Question

which statement best describes organic and inorganic molecules?

organic molecules are common in food, and inorganic molecules are used in electronics.
organic molecules are common in electronics, and inorganic molecules are used in food.
organic molecules are common in cleaners, and inorganic molecules are used in fireproofing.
organic molecules are common in fireproofing, and inorganic molecules are used in cleaners.

Explanation:

Analyze the first statement

Using the Organic Compounds and Inorganic Compounds knowledge points, we evaluate the first option. Organic molecules (like carbohydrates, proteins, and lipids) are highly common in food. Inorganic molecules (like silicon, metals, and oxides) are widely used in electronics. This statement is scientifically accurate and represents common applications.

Analyze the second statement

This statement claims organic molecules are common in electronics and inorganic molecules are used in food. While some organic semiconductors exist, inorganic materials dominate electronics. More importantly, food is primarily composed of organic matter, making this statement incorrect.

Analyze the third statement

This statement claims organic molecules are common in cleaners and inorganic molecules are used in fireproofing. While many cleaners contain organic solvents or surfactants, many common cleaners (like bleach or ammonia) are inorganic. Furthermore, this is not the best general description compared to the fundamental association of organic molecules with food.

Analyze the fourth statement

This statement claims organic molecules are common in fireproofing and inorganic molecules are used in cleaners. Organic molecules are generally combustible and not the primary basis for fireproofing, which relies heavily on inorganic minerals and compounds. Thus, this statement is incorrect.

Determine the best description

Comparing all options, the first statement provides the most accurate, standard, and balanced description of where these two classes of molecules are commonly encountered in everyday life.

Answer:

• (A) Organic molecules are common in food, and inorganic molecules are used in electronics. (Correct answer)
• (B) Organic molecules are common in electronics, and inorganic molecules are used in food.
• (C) Organic molecules are common in cleaners, and inorganic molecules are used in fireproofing.
• (D) Organic molecules are common in fireproofing, and inorganic molecules are used in cleaners.
