what are the names of the following compounds:
BF3
N2O4
P4S7?
boron trifluoride.
dinitrogen tetroxide.
tetraphosphorus septsulfide
The names of the compounds you provided are as follows:
1. BF3: Boron trifluoride.
2. N2O4: Dinitrogen tetroxide.
3. P4S7: Tetraphosphorus heptasulfide.
To determine the names of the given compounds, we need to use the rules for naming chemical compounds. Let's break down the process for each compound:
1. BF3 - This compound consists of boron (B) and fluorine (F). To name it, we use the naming system for binary compounds.
- The element with the lower electronegativity (boron) is named first and retains its original name.
- The second element (fluorine) has its name modified to end in "-ide."
Following these rules, the name of the compound BF3 is boron trifluoride.
2. N2O4 - This compound contains nitrogen (N) and oxygen (O). To name it, we again utilize the naming system for binary compounds.
- We identify the number of each element present by using Greek prefixes.
- The prefix "di-" is omitted in the case of nitrogen.
Using these rules, the name of the compound N2O4 is dinitrogen tetroxide.
3. P4S7 - This compound consists of phosphorus (P) and sulfur (S). Once more, we apply the naming system for binary compounds.
- We count the atoms of each element and use Greek prefixes to indicate the number.
- The prefix "mono-" is optional for the first element within a compound.
Applying these guidelines, the name of the compound P4S7 is tetraphosphorus heptasulfide.
Therefore, the names of the given compounds are:
- BF3 is boron trifluoride.
- N2O4 is dinitrogen tetroxide.
- P4S7 is tetraphosphorus heptasulfide.
