What is the common name and iupac name of c2h3o2k?

Answer 1

The question is not totally clear, because you've only provided the chemical formula and the question could be answered without doubt if you provide the structural formula (e.g. CH3CO2K or CH2OKCHO instead of adding all the present elements) but

I'm guessing that the structure you mean is the potassium salt of acetic acid in a structural formula represented as CH3CO2K and an attempt to give a 2D structure is here (the non-connected hydrogens have a bond with the left carbon, the non-connencted oxygen has a double bond to the right carbon):

H O

H-C-C-O-K

H

The common name is potassium acetate. The use of this trivial form (acetate for ethanoic acid in general) is so common that this is called a retained IUPAC name. The systematic name is potassium ethanoate.

There are a number of different options for C2H3O2K but they are less likely to be the desired compound, a few different options are alpha-potassium alkoxy ethanal with a structural formula of CH2OKCHO and potassium alkoxy ethylene oxide, a three membered ring with an oxygen in it (also called oxirane) with an potassium alkoxy group attachted to one of the carbons.

Hope this is satisfying!
