Name each of the following molecular compounds

Name each of the following molecular compounds.
1- SO2
2- NI3
3- BrF5
4- NO
5- N4Se4

The correct answer and explanation is :

Here are the correct names for the given molecular compounds:

1. SO₂ → Sulfur dioxide
2. NI₃ → Nitrogen triiodide
3. BrF₅ → Bromine pentafluoride
4. NO → Nitric oxide
5. N₄Se₄ → Tetranitrogen tetraselenide

Explanation:

Molecular compounds are named using a system that involves Greek prefixes to indicate the number of atoms of each element. The first element retains its elemental name, while the second element’s name is modified with an “-ide” suffix.

1. Sulfur dioxide (SO₂)

• “Sulfur” is the first element.
• “Di-” indicates two oxygen atoms.
• “Oxide” comes from oxygen.

2. Nitrogen triiodide (NI₃)

• “Nitrogen” is the first element.
• “Tri-” signifies three iodine atoms.
• “Iodide” comes from iodine.

3. Bromine pentafluoride (BrF₅)

• “Bromine” is the first element.
• “Penta-” means five fluorine atoms.
• “Fluoride” comes from fluorine.

4. Nitric oxide (NO)

• “Nitrogen” is the first element.
• “Mono-” is often omitted for the first element.
• “Oxide” comes from oxygen.

5. Tetranitrogen tetraselenide (N₄Se₄)

• “Tetra-” means four nitrogen atoms.
• “Tetra-” means four selenium atoms.
• “Selenide” comes from selenium.

The systematic naming of molecular compounds helps ensure clarity in chemistry, avoiding confusion when discussing different molecules.

Now, I’ll generate an image to illustrate these molecular compounds.
