do all compounds that contain only hydrogen, carbon and oxygen have the same properties as one another? explain

Answer 1

No, not all compounds that contain only hydrogen, carbon, and oxygen have the same properties as one another. This is because the properties of a compound depend on its molecular structure, which in turn depends on the number and arrangement of atoms within the molecule.

For example, the properties of a compound such as ethanol (CH3CH2OH) are different from those of a compound such as acetic acid (CH3COOH), even though both contain only hydrogen, carbon, and oxygen. Ethanol is a clear, colorless liquid that is commonly used as a solvent or fuel, while acetic acid is a colorless liquid that is used as a preservative, flavoring agent, and solvent.

Similarly, compare compounds such as glucose (C6H12O6) and fructose (C6H12O6). Both are simple sugars with the same molecular formula but their structures are different and hence their chemical and physical properties are different.

Thus, it is the arrangement and bonding characteristics of the atoms that will determine the properties of the compound and not just the types of atoms present.
