Question

Does methanone and ethanone exist? If yes , how? If no, why not?

Answer 1

Ketone is a functional group with a Carbon atom double-bonded with Oxygen atom.This functional group is usually placed in middle of 2 Alkane radicles.If we take the first member of Ketone family,it is noticed to be having 3 Carbon atoms and 6 Hydrogen atoms,named as Propanone.We also know that Alkanes having 1 Carbon atom are called Methane and 2 Carbon atoms are called Ethane.Hence,It is not possible to form a Ketone compound with 1 or 2 carbon atoms,as Ketone already have a carbon atom,and we need 2 radicles on either side of this functional group,which will only lead to its first member,being Propanone.
