Why does water form more hydrogen bonds than ethanol?
Danlikesanswers
The hydrogen bonding effect is weaker between ethanol molecules than between water molecules.
Both molecules have a "bent" structural pattern in the bonds formed with the oxygen, so we must consider the effects of the two surrounding groups. In water, the oxygen atom is surrounded by two hydrogen atoms, each donating equal amounts of electron density to the oxygen atom.
In ethanol, the oxygen atom is surrounded by one hydrogen atom and one organic CH2CH3 group. Principles of organic chemistry dictate that the larger organic group will donate more electron density to the electronegative oxygen atom, thereby stabilizing the dipole between the oxygen and hydrogen atoms. This results in an overall decrease in the magnitude of the partial charge on the hydrogen atom, which is the source of hydrogen bonding.

∙ 12y agoAlthough ethyl alcohol exhibits hydrogen bonding, it is less likely than water. The reason is directly related to its polarity. Water has a polarity index of 9 which makes it more electronegative than ethanol (which has a polarity index of 5.2). This
makes water more likely to form a hydrogen bond with the positive side of another molecule.

∙ 11y agoYes. The oxygen atom in ethanol has two lone pairs and these can hydrogen bond to the hydrogen atom on HO- group of another ethanol molecule.
The bp of ethanol is 78.50 C wheras (CH3)2O, dimethyl ether or methoxymethane, has a bp of -240C. this can be attributed to hydrogen bonding.

Is ethanol hydrophilic?
Surely it is. It can form hydrogen bonds with water.
What happens when ethanol reacts with bromine water?
Ethanol dissolves in water, as the polar ethanol molecules form hydrogen bonds with water molecules.
Will ethane form a hydrogen bond with water?
No ethane (C2H6) is a hydrocarbon and hydrocarbons can't form hydrogen bonds. Only molecules containing hydrogen (H) bonded with nitrogen (N), oxygen (O) or fluorine (F) can form hydrogen bonds.
Can water form hydrogen bonds form with itself?
Intermolecular bonds of water molecules are hydrogen bonds.
Why ethanol have higher boiling point than propane?
Ethanol molecules have the ability to form Hydrogen bonds with each other ( H from one molecule with O of another). Propane cannot form hydrogen bonds. Thus one needs more energy to break these bonds in order to evaporate.

Why is ethanol miscible in water?
Water molecules have hydrogen bonds between them. Since they cannot form hydrogen bonds with the ethoxyethane molecules, the ethoxyethane molcules are not soluble in water.
Why is ethanol solubile in water but propane is not?
In general terms, because (1) the carbon-oxygen and hydrogen-oxygen bonds in ethanol are much more polar than any of the bonds in propane; (2) the oxygen atom in ethanol can form hydrogen bonds with the hydrogen atoms in water, but there is not such possibility with propane; and (3) propane contains more carbon atoms per molecule than ethanol.

Three similarities between water and ethanol?
Water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
Do phospholipids form hydrogen bonds with water?

Can ethanol glycerol sucrose urea and 1-decanol hydrogen bond with water?
Yes they can. The hydroxyl groups in ethanol, glycerol, sucrose, and urea will form hydrogen bonds with water. In 1-decanol the long non-polar chain of carbon and hydrogen atoms tends to render the compound immiscible with water, but the -OH group could still theoretically form a hydrogen bond.
How do water molecules form bonds?
hydrogen bonds
How do bonds form between water molecules?
The bond between water molecules is known as a hydrogen bond.
