Which Option Correctly Matches The Chemical Formula Of A Compound With Its Name?A. N 2 O N_2O N 2 ​ O , Nitrogen Dioxide B. N O 2 NO_2 N O 2 ​ , Nitrogen Dioxide C. N O 2 NO_2 N O 2 ​ , Dinitrogen Oxide D. N 2 O N_2O N 2 ​ O , Dinitrogen Dioxide

Chemical formulas and compound names are two essential tools used in chemistry to represent and identify chemical substances. A chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound, using a single line of chemical element symbols, numbers, and sometimes other symbols, such as parentheses, dashes, brackets, and plus (+) and minus (−) signs. On the other hand, a compound name is a name given to a chemical compound based on its composition and properties.

Chemical Formulas and Compound Names: A Match Made in Heaven

When it comes to chemical formulas and compound names, there are specific rules and conventions that must be followed to ensure accuracy and consistency. One of the most important rules is that the chemical formula of a compound must match its name. In other words, the chemical formula should accurately represent the composition of the compound, and the name should accurately reflect the chemical formula.

Option Analysis

Let's analyze the options given to determine which one correctly matches the chemical formula of a compound with its name.

Option A: $N_2O$, nitrogen dioxide

Nitrogen dioxide is a compound that consists of one nitrogen atom and two oxygen atoms. The chemical formula for nitrogen dioxide is $NO_2$, not $N_2O$. Therefore, option A is incorrect.

Option B: $NO_2$, nitrogen dioxide

As mentioned earlier, the chemical formula for nitrogen dioxide is $NO_2$. This option correctly matches the chemical formula of the compound with its name. Therefore, option B is correct.

Option C: $NO_2$, dinitrogen oxide

Dinitrogen oxide is a compound that consists of two nitrogen atoms and one oxygen atom. The chemical formula for dinitrogen oxide is $N_2O$, not $NO_2$. Therefore, option C is incorrect.

Option D: $N_2O$, dinitrogen dioxide

Dinitrogen dioxide is a compound that consists of two nitrogen atoms and two oxygen atoms. The chemical formula for dinitrogen dioxide is $N_2O_2$, not $N_2O$. Therefore, option D is incorrect.

Conclusion

In conclusion, the correct option that matches the chemical formula of a compound with its name is option B: $NO_2$, nitrogen dioxide. This option correctly represents the composition of the compound and accurately reflects the chemical formula.
