maturk said:Hello, I was just thinking about the pungent smell of alcohols and if they increase as the molar mass of the alcohol increases. For example, if I were to have samples of methanol, ethanol, propan-1-ol, butan-1-ol, and pentan-1-ol all at room temperature, would the alcohol's with the highest molar mass smell more "strongly" than the ones with lower molar masses. Or would it be the other way around?
Yes, in general, the smell of alcohols does increase as molar mass increases. This is because larger molecules have more complex and stronger molecular structures, resulting in a more noticeable scent.
The molar mass of an alcohol directly correlates with its molecular weight and size. As the molar mass increases, so does the size and complexity of the molecule, leading to a stronger and more distinct smell.
Yes, there are some exceptions. For example, certain alcohols with strong odors, such as methanol and ethanol, may have a lower molar mass compared to some alcohols with weaker smells, such as octanol. This is because other factors, such as functional groups and bonding patterns, can also influence the smell of alcohols.
No, there is no specific molar mass threshold for alcohols to have a noticeable smell. The strength and intensity of the smell can vary depending on the type of alcohol and its molecular structure.
Yes, there are other factors that can affect the smell of alcohols. These include functional groups, bonding patterns, and the presence of impurities. The concentration and temperature of the alcohol can also play a role in its perceived smell.
