Isopropyl alcohol (or propan-2-ol) is also sometimes called isopropanol. That is strictly speaking an incorrect mixture of two different systems for naming alcohols. Isopropyl alcohol is the isomer of propanol which has the OH group on the middle of the three carbon atoms making up the molecule.
"They are the same substance. HOWEVER, "isopropanol" is an incorrect mix of two different naming systems. The "ol" suffix is part of the IUPAC system of nomenclature. The "iso" prefix is part of the common system of nomenclature. The two systems should not be mixed together. Alas, even authors of chemistry texts -- people who should know better if they are to lead -- make the mistake of blending the nomenclature systems."
"The actual systematic name for the stuff is 2-propanol. The name "isopropanol" is actually a combination of two naming systems, so is neither fish nor fowl. A chemist will be able to recognize the material from any of the names, though."
Lists abound. Can you put in the item that goes between the two given? Roy G Biv would know the answer to "In the spectrum: Between red and yellow" is orange.
