Q.
Which are isomers?
Jharkhand CECEJharkhand CECE 2011
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.
