Question

Draw for all constitutional isomers that have molecular formula C2H6O2​

Answer 1

C2H6O2 has two constitutional isomers: ethanol and methoxymethane.

Step-by-step explanation:

C2H6O2 is the molecular formula for ethanol. To draw all the constitutional isomers for C2H6O2, we need to consider the different ways the atoms can be arranged while maintaining the same molecular formula.

The possible constitutional isomers for C2H6O2 are:

1. Ethanol (CH3CH2OH): The simplest and most common isomer of C2H6O2, where the carbon and oxygen atoms are connected to form an alcohol functional group.
2. Methoxymethane (CH3OCH3): Also known as dimethyl ether, this isomer has a different arrangement of carbon and oxygen atoms, forming an ether functional group.

These two isomers represent the different ways C2H6O2 can be structured.

Answer 2

Step-by-step explanation:

Two or more compounds are said to be isomers if they have the same molecular formula but different structures.

Isomers that have the same molecular formula but different connectivity are largely regarded as constitutional isomers.

From below, we can see the different constitutional isomers of C2H6O2.
