Question

Name each of the following compounds.

Short answer

The compound can be named as

a- Sulfur Difluoride.

b- Dinitrogen tetroxide.

c- Iodine trichloride.

d- Tetraphosphorous hexoxide.

Step-by-step solution

Rules for naming compounds of type III

The compounds can be formed between 2 non-metals. The rules can be denoted as,

1. First is to name the first element as full name
2. If the second element is anion, it should be named
3. Prefix should be used for indication of atom number present in the molecule
4. In first element, prefix should never use.

Naming the compound of Figure a

The initial step is to count the number of each item. Number of S and F are 1 and 2. It is the covalent compounds which formed by two non-metal bonding. It can be named based on rules for covalent compound naming. The atom number involved in bonding should be indicated due to the difficult naming of covalent compounds. There is only one sulfur atom, prefix mono should be omitted. The compound contains two fluorine atom so named as sulfur difluoride.

Naming the compound of Figure b

The initial step is to count the number of each item. Number of N and O are 2 and 4. It is the covalent compounds which formed by two non-metal bonding. It can be named based on rules for covalent compound naming. There are two nitrogen atom and add “di” as prefix here. “Tetra” should also be named due to the presence of four oxygen atoms. So the compound can be named as dinitrogen tetroxide.

Naming the compound of Figure c

The initial step is to count the number of each item. Number of I and Cl are 1 and 3. It is the covalent compounds which indicates the atom number involved in bonding. There is only one iodine atom, prefix mono should be omitted. The compound contains two chloride atom so named as Iodine trichloride.

Naming the compound of Figure d

The initial step is to count the number of each item. Number of P and O are 4 and 6. It is the covalent compounds which indicates the atom number involved in bonding. There are 4 phosphorous atoms, prefix tetra should be added. The compound contains six oxygen atom so named as tetraphosphorus hexoxide.
