Questions: Name each covalent compound. Part 1 of 3 SiBr4: Part 2 of 3 SF2: Part 3 of 3 N2O:

Solution Steps

To name $\mathrm{SiBr}_{4}$, we follow the rules for naming covalent compounds:

1. The first element is named first, using the full element name.
2. The second element is named as if it were an anion (root + "ide").
3. Prefixes are used to denote the number of atoms of each element present in the compound (except the prefix "mono-" is not used for the first element).

For $\mathrm{SiBr}_{4}$:

• The first element is silicon.
• The second element is bromine, which becomes bromide.
• The prefix for four is "tetra-".

Thus, $\mathrm{SiBr}_{4}$ is named silicon tetrabromide.

To name $\mathrm{SF}_{2}$, we follow the same rules:

1. The first element is named first, using the full element name.
2. The second element is named as if it were an anion (root + "ide").
3. Prefixes are used to denote the number of atoms of each element present in the compound.

For $\mathrm{SF}_{2}$:

• The first element is sulfur.
• The second element is fluorine, which becomes fluoride.
• The prefix for two is "di-".

Thus, $\mathrm{SF}_{2}$ is named sulfur difluoride.

To name $\mathrm{N}_{2} \mathrm{O}$, we follow the same rules:

1. The first element is named first, using the full element name.
2. The second element is named as if it were an anion (root + "ide").
3. Prefixes are used to denote the number of atoms of each element present in the compound.

For $\mathrm{N}_{2} \mathrm{O}$:

• The first element is nitrogen.
• The second element is oxygen, which becomes oxide.
• The prefix for two is "di-" and for one is "mono-".

Thus, $\mathrm{N}_{2} \mathrm{O}$ is named dinitrogen monoxide.
