How do you know which compound has the highest viscosity?
Viscosity is governed by the strength of intermolecular forces and especially by the shapes of the molecules of a liquid. Liquids whose molecules are polar or can form hydrogen bonds are usually more viscous than similar nonpolar substances.
Which molecule has the highest viscosity?
ethylene glycol
The molecule with the MOST hydroxyl groups, ethylene glycol, has the HIGHEST viscosity.
Does ethanol have a high viscosity?
We found in an experiment using Ostwalds method that ethanol is more viscous than water, which is already surprising as water has stronger intermolecular bonds than ethanol as @MaxW pointed out. The mixture of both substances furthermore is significantly more viscous than both individual substances.
What is the viscosity of ethanol?
0.001095 1.095
Absolute (dynamic) viscosity values for some common fluids.
| Fluid | Absolute Viscosity | |
|---|---|---|
| (N s/m2, Pa s) | (centipoise, cP) | |
| Alcohol, ethyl (ethanol) | 0.001095 | 1.095 |
| Alcohol, methyl (methanol) | 0.00056 | 0.56 |
| Alcohol, propyl | 0.00192 | 1.92 |
Which hydrocarbon has the highest viscosity?
octane
Because octane has a longer carbon chain than pentane, the dispersion forces are even stronger, and octane has a higher viscosity. In conclusion, the alkane with the greatest viscosity is octane, or answer choice (A).
Why does ethanol C2H6O have a higher viscosity than octane C8H18 )?
Which is the best reason why ethanol (C2H6O) has a higher viscosity than octane (C8H18)? Ethanol can make strong hydrogen bonds.
How can the viscosity of ethanol be increased?
Ethanol viscosity increases with addition of ethyl cellulose.
Which of the following liquids would have the highest viscosity at 25oc?
From the given compounds C2H5OH will have the highest viscosity.
What is the molecular weight of isopropyl alcohol?
Isopropyl alcohol PubChem CID 3776 Synonyms isopropanol Isopropyl alcohol 2-Propanol Molecular Weight 60.10 Date s Modify 2021-08-28 Create 2004-09-16
What is the relationship between viscosity and temperature?
(Section 11.3) As temperature increases, viscosity decreases; they are inversely related. The same attractive forces that cause surface molecules to be difficult to separate (high surface tension) cause molecules elsewhere in the sample to resist movement relative to each other (high viscosity).
What are the attractive forces of boiling point in HCl?
By analogy to attractive forces in HCl, the trend will be dominated by dispersion forces, even though four of the molecules are polar. The order of increasing boiling point is the order of increasing molar mass and increasing strength of dispersion forces.
