In organic chemistry, these terms have a lot of importance. Although they seem pretty much similar, they have a vast difference in their nature and functionality. Some elements are stable at room temperature and can occur in different formulas or different arrangements. It can be made up of a single element or several elements.

A single element’s allotropes can exist in a variety of states. Allotropy, on the other hand, is limited to solid materials. They do have comparable characteristics as a result of their composition. It’s only applicable to elements, not compounds.
Isomers are chemical compounds that have a similar molecular formula but differ in their structural formulae. Their characteristics aren’t always the same. The functional group determines this.
