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

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.

Not all compounds that contain only hydrogen, carbon, and oxygen have the same properties as one another. The properties of a compound depend on its molecular structure, which is determined by the arrangement and bonding of its atoms.

While there may be some similarities in properties among certain compounds that share the same functional groups or have similar molecular structures, such as alcohols or ketones, the specific arrangement and number of atoms can greatly affect the properties.

For example, consider methane (CH4), ethanol (C2H6O), and acetic acid (CH3COOH). These compounds have different molecular structures and therefore exhibit different properties. Methane is a gas at room temperature, while ethanol is a liquid and acetic acid is a liquid at room temperature. They also have different boiling points, melting points, densities, and solubilities in various solvents.

Therefore, it is important to analyze the specific molecular structure of a compound to understand its properties accurately.
