Which are isomers?

Question

Which are isomers? (A) Ethyl alcohol and dimethyl ether (B) Acetone and acetaldehyde (C) Propionic acid and propanone (D) Methyl alcohol and dimethyl ether

Tardigrade Admin · Accepted Answer

Isomers have the same molecular formula but different structure. Ethyl alcohol (C2H5OH) and dimethyl ether (CH3OCH3) both have the same molecular formula (C2H6O), so these are isomers.

Ethyl alcohol and dimethyl ether

Acetone and acetaldehyde

Propionic acid and propanone

Methyl alcohol and dimethyl ether

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