Comparing Chemical Properties and Structures

The video tutorial explains two valid Lewis structures for C2H6O: dimethyl ether and ethanol. Both structures use the same number of electrons and satisfy the outer shells of the atoms, making them isomers with different chemical and physical properties. The tutorial highlights the full valence electron shells for carbon, oxygen, and hydrogen in these structures.

What is the name of the compound when the oxygen atom is placed between the two carbon atoms in the C2H6O structure?

• Ethanol

• Propane

• Dimethyl ether

• Methanol

Which compound is formed when the oxygen atom is on the outside with hydrogen attached in the C2H6O structure?

• Dimethyl ether

• Ethanol

• Acetone

• Butanol

What term is used to describe compounds with the same chemical formula but different structures?

• Isomers

• Allotropes

• Isotopes

• Polymers
