Why is the dipole moment of water less than the dipole moment of alcohol?

Both CH2Cl2 and CHCl3 are bonded in a tetrahedral structure. The net dipole moment of CHCl3 is less than that of CH2Cl2 because the individual C-Cl dipole moments of CHCl3 cancel out each other to a greater extent.

∙ 13y agoThis has to do with the fact that one of the bond in an alcohol is C-O rather than both being O-H. The difference in electronegativity between carbon and oxygen is less than the difference between hydrogen and oxygen. This causes less electron density to be on the oxygen in alcohols than in water which is why the dipole moment is less.

Why phenol has lesser dipole moment than alcohol?
As we know that dipole moment of polar molecules is greater than non-polar. In other words, in molecules where charge separation is more, it is more polar and hence having more dipole moment. In phenol, due to resonance, there is positive charge on oxygen. So there is no more charge difference between carbon of ring and oxygen of OH group. This is the reason, it has less dipole moment.
Why Nh3 and Nf3 has high dipole moment?
This is because in ammonia the direction of resultant dipole is towards lone pair and hence it has high dipole moment but in case of NF3 the direction of resultant dipole moment is opposite to the lone pair and hence the dipole moment gets less.
What is dipolar nature of water?
A dipole refers to two electrostatic charges which are separated by distance. In chemical compounds a dipole refers to unequal distribution of charge across a molecule that leads to an effective dipole often due to vector sum of bond dipoles.
Why is water mixed alcohol lighter than fresh water?
The density of alcohol is less than that of water.
Why do polar substance have a high dielectric constant?
Water, due to its polar nature, has a large dielectric constant. Therefore, water molecule has a very large electric dipole moment and is forced to rotate to respond to an alternate external electric field. Hence water as a liquid has a very large dielectric constant i.e. 80. Mica on the other hand is less polar as water and hence has low dielectric constant.

What is the much more polar solvent?
Formamide is the most polar solvent. It has a dipole moment of 3.73 and a dielectric constant of 109. As a comparison, water has a dipole moment of 1.85 and a dielectric constant of 80. The higher the dipole moment value and the dielectric constant, the more polar the solvent. At the opposite, the less polar solvents are hexane, benzene and carbontetrachloride.
Why o-chlorophenol has less dipole moment than o-fluorophenol?
The reason for the larger dipole moment of o-fluorophenol is because F is more electronegative than Cl.

Is diethylether polar?
All ethers are polar molecules. They are less polar than an equivalent alcohol or ester, but the lone electrons on the oxygen atoms makes polar bonding likely.
How is it that 10 milliliter of alcohol combined with 10 milliliter of water equal 19 milliliter?
The answer has to do with the different sizes of the water and alcohol molecules. Alcohol molecules are smaller than water molecules, so when the two liquids are mixed together the alcohol falls between the spaces left by the water. It's similar to what happens when you mix a liter of sand and a liter of rocks. You get less than two liters total volume because the sand fell between the rocks, right? Think of miscibility as 'mixability' and it's easy to remember. Fluid volumes (liquids and gases) aren't necessarily additive. Intermolecular forces (hydrogen bonding, London dispersion forces, dipole-dipole forces) also play their part in miscibility, but that's another story.
Why is the dipole moment of hydrogen iodide is less than the dipole moment of hydrocloric acid?
Well, this may be due to the fact that Cl is more electronegative than Iodide, if you notice the periodic chart, an element's electronegativity increases towards the upper right of the chart, and Iodide is far at the bottom of the halogens. NOW where people get confused is because of the size of Iodide, meaning that it should have a great dipole moment because Iodide is bigger than Cl therefore the charges would be more unevenly shared, but HCl wins because of the more electronegativity.

What happens if you mix chlorine bleach and rubbing alcohol?
Answer#1The alcohol, being less dense will float on top. They do not react. This answer is nonsense. Alcohol and bleach will mix, and they react, but not in a way that will kill you. Alcohol is less dense than water or bleach (water plus sodium hypochlorite) but alcohol and water do mix... mixed drinks, anyone?
Is water more or less viscous than spirits?
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.
