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.
