In order for a molecule to be IR active, the vibration must produce an oscillating dipole. This usually means that the bond (or bonds) in question have are polar to begin with so that they have a dipole. Therefore symmetrical molecules like O2 and N2 are not IR active, but molecules like H2O with polar bonds are IR active.

∙ 11y agoAn IR-active molecule is one that has a permanent dipole, which means the partial negative and positive charges never cancel each other. For example H2O, HCl and CO are active. An inactive molecule has two of the same molecules such as O2, N2, F2, etc.

To absorbe IR radiation, a molecule must undergo a net change in dipole moment as it vibrate or rotate.when the molecule are "IR active". e.g. H2O, HCl, CO etc.
A molecule that do not absorbe IR radiation and net change in dipole moment occur during vibration and rotation are said to be'' IR inactive". e.g. Cl2, O2 etc. Symmetrical carbon dioxide and triple bond are IR inactive.

What are the name of active and inactive?
Active is an expression of functional..means it is capable of doing something!(active molecules) and its opposite is inactive which lacks the activity.
How do you determine the molecule is microwave active or inactive?
It is determined by whether the molecule is polar or nonpolar. Nonpolar molecules do not absorb radiation in the microwave region; therefore, they are microwave inactive. Polar molecules are microwave active.
How do you distiguish for the optically active and in active?
First of all we should know what optically active molecules are "Those molecules which possess asymmetric(chiral) carbon atoms have the ability to rotate the plane polarized light(light of one wavelength having its electrical character vibrating in one direction only) to the left or to the right are known as Optically active molecules" while those molecules not following the former scenario are known as Optically Inactive molecules. All in all molecules having asymmetric carbon atoms are known as optically active molecules for example glucose(rotate plane polarized light to the left) & fructose(rotate plane polarized light to the right) are optically active molecules. While molecules lacking asymmetric carbon atoms are optically inactive molecules for example water is optically inactive. And that's how we can distinguish between these two molecular classifications.
How would you use inactive in a sentence?

What are caged molecules and what are they used for?
Caged molecules are molecules that are temporarily inactive due to a protecting group that can be selectively removed to activate the molecule for a specific reaction or function. They are commonly used in chemical biology to study cellular processes with precise spatial and temporal control.
Is pepsin a polypeptide?
Pepsinogen is the proenzyme of pepsin. Pepsinogen is inactive, it is metabolized into the enzyme pepsin which break down proteins into small molecules.
