Acetic acid is not the oldest compound. While it has been known since ancient times (for example, vinegar is a dilute solution of acetic acid), there are many other compounds that have been discovered or used even earlier in human history, such as water, salt, and various minerals.
Isobars are atoms of different elements that have the same atomic mass but different atomic numbers. Isotones are atoms of different elements that have the same number of neutrons but different atomic numbers. Isoelectronics refers to ions or molecules that have the same number of electrons.
The addition of hydrogen occurs in the presence of a Nickel catalyst. The catalyst is used to break the bonds such as double or triple bonds present in the unsaturated hydrocarbons, thereby changing it into saturated hydrocarbons. The process is called Hydrogenation.
