Why has Propane-123-triyl triethanoate much larger molecules than propane-123-triol and yet it is much less viscous?

ummmm i don't know , the amount of O-H bonds is higher. A higher viscosity is down to the strength of hydrogen bonding. Intermolecular forces must be broken for fluids to flow more freely and with hydrogen bonding being the strongest imf there is...................

Propane-123-triyl triethanoate has larger molecules due to the presence of three ethanoate groups attached to the propane backbone, increasing molecular weight. The larger size does not necessarily translate to higher viscosity because the ethanoate groups can create space between molecules, reducing intermolecular forces, and making it less viscous compared to propane-123-triol.

Why h2so4 is viscous?
There is hydrogen bonding between H2SO4 molecules. Hence it has a associatedstructureand due to this H2SO4 is viscous.
Why concentrated sulfuric acid is viscous in nature?
Concentrated sulfuric acid is viscous due to strong intermolecular forces between its molecules. These forces cause the molecules to stick together, making it difficult for them to flow past each other easily. Additionally, sulfuric acid is a polar molecule, further contributing to its viscous nature.
What happens to the oil molecules when it is heated?
When oil is heated, the molecules gain energy and move more vigorously. This causes the oil to expand and become less viscous. If it continues to be heated to its smoking point, the molecules can break down and create harmful byproducts.
Which is more viscous pure water or saline water?
The saline water is more viscous.
What is a Thick and gooey liquid?
Viscous
Would you expect larger or smaller molecules to be components of a more viscous liquid?
Larger molecules tend to contribute to higher viscosity in liquids because they have more surface area to interact with neighboring molecules, resulting in stronger intermolecular forces that impede flow. Smaller molecules typically have lower viscosity as they facilitate easier movement between molecules.
Why h2so4 is viscous?
There is hydrogen bonding between H2SO4 molecules. Hence it has a associatedstructureand due to this H2SO4 is viscous.
Is blood Viscous or non viscous?
Blood is considered viscous because it has a thickness or stickiness that affects its flow. This viscosity is important for functions such as maintaining blood pressure and allowing it to flow through blood vessels efficiently.
Why a liquid is less viscous at high temperature?
When the liquid is at high temperature, the molecules of liquid have more energy & spread further apart. This enables the molecules to move around much more in the liquid which makes it less viscous or fluid.
Explain why coconut oil does not mix in water?
because the molecules in coconut oil are not close and it is a viscous liquid
Explain what determines the viscosity of a liquid?
the shape and size of the molecules that the fluid consists of, if they are big, wavy molecules then the liquid will be viscous because the molecules struggle to move over each other.
What properties do liquid and gases have due to the movement of their molecules?
Liquids and gases are amorphous (shapeless), viscous (can flow), and diffuse (have internal space) due to the movement of their molecules.
How does the viscosity of a fluid affect its rate of convection?
The more viscous a substance is, the closer together its molecules are, the more energy required to excite the molecules. Therefore, higher viscosity equals a lower excitability.
Does ketchup have viscous?
Yes, ketchup is a viscous fluid. Viscosity refers to a fluid's resistance to flow, and the thickness of ketchup makes it a good example of a viscous liquid.
Which is more reactive and why monohydroxy alcohol or polyhydroxy alcohol?
Polyhydroxy alcohols are generally more reactive than monohydroxy alcohols because they have multiple hydroxy groups available for reactions, increasing the likelihood of chemical interactions. The presence of multiple hydroxy groups allows for a greater range of reactions to occur, leading to increased reactivity compared to monohydroxy alcohols.
Is salt viscous?
Molten salt is viscous.
Is composite volcano lava viscous or fluid?
