The name of N2S3 is:
nitrogen tetrasulfide
nitrogen sulfide
Dinitrogen trisulfide
The Correct Answer and Explanation is :
The correct name for ( N_2S_3 ) is Dinitrogen trisulfide.
Explanation:
The naming of chemical compounds follows certain conventions based on the rules of chemical nomenclature. In the case of molecular compounds (also known as covalent compounds), the rules for naming are based on the number of atoms of each element involved. Here’s how we apply these rules to ( N_2S_3 ):
- Prefix for Number of Atoms:
- “Di-“ refers to 2 atoms.
- “Tri-“ refers to 3 atoms.
So, we use the prefixes “di-” for nitrogen (N) and “tri-” for sulfur (S).
- Naming the Elements:
- The first element in the compound is nitrogen (N). The prefix “di-” indicates that there are 2 nitrogen atoms.
- The second element is sulfur (S). The prefix “tri-” indicates that there are 3 sulfur atoms.
- Order of Naming:
- The more electropositive element (usually the one to the left on the periodic table) is named first. In this case, nitrogen is named first, followed by sulfur.
- Final Name:
- Combining the prefixes and elements, the correct name for ( N_2S_3 ) is Dinitrogen trisulfide.
The other names you provided, “nitrogen tetrasulfide” and “nitrogen sulfide,” do not apply here because they either misrepresent the number of sulfur atoms or omit the proper prefixes. “Nitrogen tetrasulfide” would imply 4 sulfur atoms (which corresponds to ( N_2S_4 )), and “nitrogen sulfide” would imply a 1:1 ratio of nitrogen to sulfur, which corresponds to ( NS ) (not ( N_2S_3 )).
Thus, the correct name for the compound ( N_2S_3 ) is Dinitrogen trisulfide.
