Question

Draw two constitutional isomers that share the molecular formula C2H6O.

Answer 1

Constitutional isomers with the formula C2H6O are ethanol (an alcohol) and dimethyl ether (an ether). They have the same molecular formula but different structures and functional groups.

Step-by-step explanation:

The student has asked to draw two constitutional isomers that share the molecular formula C2H6O. Constitutional isomers are compounds that have the same molecular formula but differ in the way the atoms are connected to each other.

For the molecular formula C2H6O, the two constitutional isomers are:

1. Ethanol (CH3CH2OH) - This isomer has a hydroxyl group (-OH) attached to an ethane backbone, making it an alcohol.
2. Dimethyl ether (CH3OCH3) - This isomer features an oxygen atom between two methyl groups, which classifies it as an ether.

These two compounds illustrate the concept of isomerism where the functional groups and connections between atoms result in molecules with distinct properties despite sharing the same molecular formula.
