Chapter 5: Problem 50

Are all molecules also compounds? Explain.

Short Answer

Expert verified
No, not all molecules are compounds. While all compounds are considered molecules, there are some molecules that are not compounds because they consist of atoms of the same element bonded together, rather than a combination of different elements.

Step by step solution

01

Define Molecules

Molecules are formed when two or more atoms join together chemically (by sharing electrons). A molecule can either consist of atoms of the same element (such as O2, or molecular oxygen: two oxygen atoms bonded together), or a combination of different elements (such as H2O, or water: two hydrogen atoms bonded to one oxygen atom).
02

Define Compounds

Compounds are a type of molecule that consists of two or more different elements in definite proportions by mass, and they are chemically bonded together. For example, water (H2O) is a compound because it consists of two hydrogen atoms and one oxygen atom bonded together in a fixed proportion.
03

Compare Molecules and Compounds

All compounds are molecules because they are formed by the bonding of atoms. However, not all molecules are compounds, as some molecules can be composed of atoms of the same element. An example of a molecule that is not a compound is oxygen gas (O2), which consists of two oxygen atoms bonded together but does not involve any different elements.
04

Conclusion

No, not all molecules are compounds. While all compounds are considered molecules, there are some molecules that are not compounds because they consist of atoms of the same element bonded together, rather than a combination of different elements.

Most popular questions from this chapter

Draw a dot diagram for the molecule \(\mathrm{O}_{3}\), ozone, the molecule in our upper atmosphere that protects us from the Sun's harmful ultraviolet electromagnetic radiation. (Hint: Only the middle oxygen atom forms bonds with the two other oxygen atoms.)

Ethers are compounds of \(\mathrm{C}, \mathrm{H}\), and \(\mathrm{O}\) that are often used as solvents. One particular ether molecule has the formula \(\mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O} .\) The structure is such that both carbons are attached to the oxygen atom, and there are no \(\mathrm{O}-\mathrm{H}\) bonds. Starting with dot diagrams for the atoms, draw a dot diagram for this ether molecule. How many bonding pairs does the molecule have? How many lone pairs?

What is an ionic bond? How does it differ from a covalent bond, and how is it similar to a covalent bond?

Explain what is meant by resonance forms.

The use of chlorofluorocarbons (CFCs) in airconditioning and refrigeration systems has been linked to depletion of the ozone layer of the atmosphere. One of the most widely used CFCs, freon-12, has the formula \(\mathrm{CF}_{2} \mathrm{Cl}_{2}\). It is now being replaced with a compound that has the formula \(\mathrm{CH}_{2} \mathrm{FCH}_{3}\). Draw the dot diagrams for \(\mathrm{CF}_{2} \mathrm{Cl}_{2}\) and \(\mathrm{C} \mathrm{H}_{2} \mathrm{FCH}_{3}\). (Hint: In \(\mathrm{CH}_{2} \mathrm{FCH}_{3}\), the carbons bond to each other, and one of them bonds to fluorine.)
