Ethanol has dipole moment in the C-O bond and the carbon part of it has London Disperse force, whereas water has only hydrogen bond. So ethanol has more intermolecular force than water, making it more viscous than water.
Meanwhile, ethanol has less boiling point than water because London disperse force is easily disrupt by heat.

∙ 14y agoDrinking alcohol (ethanol) and a lot of other simple alcohols are more volatile than water because they are less polar. Water's higher polarity means that each water molecule "sticks" to other water molecules more tightly, so each molecule is more likely to stay in the liquid phase, and it takes a great deal of energy to break these attractions and force water into the gas phase (why the boiling point of water is so unusually high for such a small molecule). Ethanol is much less "sticky" and more readily enters the gaseous phase, hence it is more volatile.

How viscosity can be explain to a lay man?
Viscosity has to do with the thickness of a fluid. Honey is more viscous than water for example. Blood becomes more and more viscous as it dries.
Would you expect larger or smaller molecules to be components of a more viscous liquid?
Larger molecules make a liquid more viscous. Larger molecules occupy more space compared to smaller molecules which makes a liquid thicker.
Does a balloon go farther with more or less water?
Less water ;)
What is an example of high and low viscous material?
Viscosity is a measurement of how much a liquid resists flow or deformation -- viscous liquids tend to move more slowly than non-viscous liquids. An example of a highly viscous liquid might be honey or molasses; vinegar and water have low viscosity.
What is relation between viscocity and density?
The more dense a substance is, the more viscous it is.
Is water more viscous than vegetable oil and methylated spirits?
Water is more viscous than methylated spirits, and vegetable oils are more viscous than water.
Can a viscous fluid be less dense then fresh water?
Yes, for example oil is less dense than water even though it is more viscous.
Which is more viscous pure water or saline water?
The saline water is more viscous.
What is meant by a viscous liquid?
Viscosity is a measure of the thickness or how runny a liquid is. More viscous means thicker and syrup-like. Less viscous means more runny and more like water.
Why HF is less viscous than water?
due to more h-bonding in water as compared to Hf
Why HF less viscous than water?
due to more h-bonding in water as compared to Hf
Define volatile and viscous?
Viscous means how thick a LIQUID is and how tightly the particles are packed together if the liquid is thick(less runny) it is more viscous if the liquid is thin(more runny) it is less viscous
Which is more viscous toothpaste or milk?
Toothpaste is more viscous because it flows less freely than milk.
What is the definition of viscosity?
Viscosity is a fluid's resistance to flow. Fluids becomes less viscous as the liquid's temperature increases, becoming more viscous as the fluid gets cooler. A viscous fluid is sticky, thick and syrupy to a greater or lesser extent. Examples Treacle is quite viscous, but water is not. Hot engine oil is less viscous ('thinner') and runs more quickly and smoothly than cold engine oil.
Petroleum in Albertas oil snads is more viscous than mollasses and certainly too viscous to pump How did they solve the problem?
Added heat. Warm petroleum is far less viscous than cold. Pumps like water.
How does honey flow more slowly than water?
It is due to the difference in viscosity . Honey is more viscous than water due to strong inter molecular forces. On the other hand water is less viscous than honey . Therefore, it's easier to pour water as compared to honey . :-)
What does more viscous mean?
Have a look here http:/dictionary.reference.com/browse/viscousViscosity it how thick or thin a fluid is.The thicker a fluid is the more viscous. If the fluid is less viscous it is thinner. A fluid is liquid AND gas. If a fluid is hotter is gets less viscous but if it is cooler it will be more viscous.
