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 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 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.
Why do esters with higher molecular weight do not have strong fragrances?
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.

What is the purpose of esters in humans?
Esters with low molecular weight are commonly used as fragrances and found in essential oils and pheromones. Wikipedia gave me the above.

What is the molecular weight of cellulose acetate butyrate?
Typically 20,000 to 60,000. Cellulose is natural macro molecule without any specific size or molecular weight. The same applies to the esters of cellulose.

What is the molecular weight and molecular formula of potassium humate?
molecular structur C9H8K2O4molecular weight: 258.35
If you have molecular weight how can you find equivalent weight?
To determine the equivalent weight from the molecular weight, you need to divide the molecular weight by the valence (or charge) of the compound. For example, for a compound with a molecular weight of 100 g/mol and a valence of 2, the equivalent weight would be 50 g/equiv.
