Identify the correct formula for each of the following compounds:

1. Carbon tetrabromide
- A. [tex]$CBr_4$[/tex]
- B. [tex]$C_4Br$[/tex]
2. Chlorine monofluoride
- A. [tex]$ClF$[/tex]
- B. [tex]$Cl_1F_1$[/tex]


Sagot :

To identify the correct formula for each of the given compounds, we need to follow the rules of chemical nomenclature for naming molecular compounds:

1. Carbon tetrabromide:
- The prefix "tetra-" indicates four bromine atoms.
- The carbon atom does not need a prefix when there is only one atom.
- Therefore, the correct formula is [tex]\( \text{CBr}_4 \)[/tex].

2. Chlorine monofluoride:
- The prefix "mono-" indicates one fluorine atom.
- The chlorine atom does not need a prefix when there is only one atom.
- Therefore, the correct formula is [tex]\( \text{ClF} \)[/tex].

Here's a summary of the correct formulas for each compound:
- Carbon tetrabromide: [tex]\( \text{CBr}_4 \)[/tex]
- Chlorine monofluoride: [tex]\( \text{ClF} \)[/tex]

Using the given list, the correct formulas are:
1. Carbon tetrabromide -> [tex]\( \text{CBr}_4 \)[/tex]
2. Chlorine monofluoride -> [tex]\( \text{ClF} \)[/tex]

These formulas correspond to the typical rules of chemical nomenclature for naming molecular compounds.
