<prompt> In chemistry, isomers are ions or molecules with identical formulas but distinct structures. Isomers do not necessarily share similar properties. Two main forms of isomerism are structural isomerism or constitutional isomerism and stereoisomerism or spatial isomerism. Mubvunzo: Ndeapi mafomu ekutanga e isomerism anozivikanwa se?  <response>: structural isomerism kana constitutional isomerism uye stereoisomerism kana spatial isomerism
