Ethylene glycol is more viscous than ethyl alcohol because ethylene glycol contains two O-H groups (ethyl alcohol contains one O-H group). This results in stronger hydrogen bonding between ethylene glycol molecules.
Which alcohol is viscous in nature?
Methyl alcohol, ethyl alcohol, and isopropyl alcohol are free-flowing liquids with fruity odours. The higher alcohols—those containing 4 to 10 carbon atoms—are somewhat viscous, or oily, and they have heavier fruity odours.
Is ethyl alcohol more viscous than glycerol?
Because of larger number of intermolecular hydrogen bonding (three per molecule) in case of glycerol (CH2OH-CHOH0CH2OH) as compared to ethanol (CH3CH2OH), the attraction between molecules of glycerol is more than that between molecules of ethanol. Due to this glycerol is more viscous than ethanol.
Which is more viscous water or ethyl alcohol?
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 alcohol?
Absolute (dynamic) viscosity values for some common fluids.
|(N s/m2, Pa s)||(10–4 lb/s ft)|
|Alcohol, ethyl (ethanol)||0.001095||7.36|
|Alcohol, methyl (methanol)||0.00056||3.76|
Which is the most viscous?
Out of all the liquids I tested (honey, water, milk, cooking oil, glycerin, hand sanitizer, and syrup), honey is the most viscous and milk is the least.
Which is the least viscous?
The least viscous at any temperature must be superfluid liquid helium.
Which is more viscous glycerol or glycol?
i) Glycerol (propane 1,2,3 triol) is more viscous than ethylene glycol ( ethane 1,2, diol). … The viscosity depends on the amount of hydrogen bonding between molecules, and the more -OH bonds there is more hydrogen bonding can occur. So glycerol is the most viscous.
Is ethanol viscous?
Ethanol is more viscous than water but not by much. Of course it will depend on temperature. But at 20°C, viscosity of ethanol (C2H5OH) is 0.0119 dynes/cm ^2 per unit velocity gradient) and water is 0.01002 or 16% less than alcohol.
Which is more viscous glycol or water?
The structures of ethylene glycol and water are shown below. Based on these structures, ethylene glycol has more sites for hydrogen bonding than water. For this reason, has stronger intermolecular forces of attraction and much more viscous than water.
Which is more viscous ethanol or isopropanol?
At room temperature (betwen 293 and 298 Kelvins), isopropanol has a higher viscosity. More precisely, ethanol has a viscosity of 1.2160 mPas at 293K, and 1.0903 at 298K; isopropanol has a viscosity of 2.3810 at 293K and 2.0520 at 298.15K.
Which is more viscous ethanol or methanol?
Ethanol C2H5OH (2 carbons) is more viscous than methanol (1 carbon). As a rule, viscosity of these compounds containing carbon chains (like the mother hydrocarbon chains) increase as the chain becomes longer.
Which is most viscous liquid?
Water, mercury, and kerosene are easily flowable liquids so they can be eliminated. So, glycerine is found to be the most viscous liquid.
What material is more viscous?
Viscosity is a material property which describes the resistance of a fluid to shearing flows. It corresponds roughly to the intuitive notion of a fluid’s ‘thickness’. For instance, honey has a much higher viscosity than water.
Is ethanol a viscous liquid?
Ethanol, also called ethyl alcohol, is a volatile, flammable, colorless liquid with the structural formula CH3CH2OH (often abbreviated as C2H5OH or C2H6O). … Best known as the type of alcohol found in alcoholic beverages, it is also used in thermometers, as solvent and as a fuel.
