In order to have a smell a substance must have Four different properties.
1. It must be volatile so it gets in the air and makes it to your nose.
2. It is water soluble and can make it past the mucous layer in your nose.
3. It is fat soluble and can make it past the lipid membrane in your nose cells.
4. There is a receptor in your nose that can sense it.
Lower molecular weight esters are very volatile and quickly fill up the air in the room. They are both fat soluble and mildly water soluble. They fit easily into certain receptors in your nose and so they have a strong smell.
Higher molecular weight esters are not very volatile. They mostly stay in solid or liquid form but do not turn into gases. They often don't ever get to your nose. They are fat soluble, but not water soluble, so even if they do get to your nose, they can't pass through the mucous layer to get to your scent receptors. They are also very bulky and so they do not fit very well into the scent receptors because they are too big. All of these things contribute to them having a mild smell if any smell at all.

Why do esters with higher molecula weight do not have strong fragrances?
Esters with higher molecular weights have heavier molecules, which makes it difficult for them to evaporate and reach our noses to create a strong fragrance. Lighter molecules are more volatile and can easily reach our olfactory receptors, creating a stronger scent perception.
Why do esters with high molecular weight do not have strong fragrances?
Esters with high molecular weight are larger molecules that are less volatile, making it harder for them to reach the olfactory receptors in our nose and produce a strong fragrance. Additionally, their larger size may also lead to interactions with other molecules that can mask or alter their scent profile.
Why do esters have a high boiling point?
Esters have higher boiling points compared to alkanes of similar molecular weight due to their polar nature, which allows for the formation of dipole-dipole interactions between molecules. Additionally, esters can engage in hydrogen bonding, further increasing their boiling points.
Ester name of durian?
Durian esters are compounds responsible for the fruit's unique smell and taste. These esters include ethyl isovalerate, ethyl 2-methylbutyrate, and ethyl butanoate, among others. The combination of these esters gives durian its characteristic strong aroma that some people find unpleasant.
If both molecular solids and network solids contain covalent bonds why do network solids have such higher melting points than molecular solids?
Network solids have a three-dimensional structure with strong covalent bonds throughout, leading to a higher melting point compared to molecular solids which have weaker intermolecular forces. In network solids, a larger amount of energy is required to break the extensive network of covalent bonds, resulting in a higher melting point.

Why are some fragrances stronger than others?
Some fragrances are stronger than others because of the flower or ingredient used to create the particular scent. Some fragrances have higher potency due to the ingredient of a very strong scented flower extract that was added, while others like vanilla are on the softer scent side.
What pink colored flower has a strong fragrance?
Yes, there are. There are several varieties of pink roses that have strong fragrances.

Why does sugar have a higher solubility rate than salt?
because the inter molecular bonds in sugar are very weaker, where as salt will be haaving strong ionic bonds.
What is a sentence using the word molecular?
The electron microscope can show a picture of the molecular level. Molecular bonds are quite strong.

In network solids, a larger amount of energy is required to break the extensive network of covalent bonds, resulting in a higher melting point.
What are the comparative strengths of ionic - and molecular bonds?
Ionic bonds are strong, molecular bonds are relatively weak.
How do ionic and molecular compounds differ in physical properties?
Ionic compounds have higher melting and boiling points than molecular compounds due to the strong electrostatic forces between ions. Ionic compounds are usually solid at room temperature, while molecular compounds can be solid, liquid, or gas. Ionic compounds conduct electricity when dissolved in water, while molecular compounds do not.
