    Which are isomers?

    A)  Ethyl alcohol and dimethyl ether

    B)  Acetone and acetaldehyde

    C)  Propionic acid and propanone

    D)  Methyl alcohol and dimethyl ether

    Correct Answer: A

    Solution :

     Isomers have the same molecular formula but different structure. Ethyl alcohol \[({{C}_{2}}{{H}_{5}}OH)\] and dimethyl ether \[(C{{H}_{3}}OC{{H}_{3}})\] both have the same molecular formula \[({{C}_{2}}{{H}_{6}}O),\] so these are isomers.
