Because of the sum of polarities: there are a manifold of equally charged ions in an ethanol molecule compared to water that repel each other.
Ch3cooch2ch3 + h2o
When CH3CH2OH and H2O are mixed together to form a homogenous solution, CH3CH2OH forms additional hydrogen bonding with water molecules.
This reaction is:CH3COOCH2CH3 + H2O ↔ CH3COOH + CH3CH2OHThe products are acetic acid and ethanol.
C2H4(g) + H2O(g) → CH3CH2OH(l)
In HF molecule hydrogen bonding is the strongest. The reason is that the partial positively charged hydrogen atom is entrapped between the two highly electronegative fluorine atoms.
H2O has a stronger bond then CaO because H2O is a covalent compound (made up of two nonmetals), whereas CaO is an ionic compound (made up of both a metal and nonmetal), and covalent bonds are stronger then ionic bonds.
Ch3cooch2ch3 + h2o
The ion-ion bond in CaSO4 is stronger than in NaCl because of the higher charges on the cation and anion. Be careful in making this argument. The ion-dipole forces of Ca2+ -H2O and SO42- - H2O might actually be stronger than that of Na+ -H2O and Cl- -H2O due to the high charges on Ca2+ and SO42- . However the strengths of the ions-dipole interactions do not match (or exceed) the strength of the Ca2+ -SO42- ionic bond.

Oxygen has a stronger bond to H than S does, therefore it requires more energy to break the H-O bond = oxygen having the higher boiling point
The equation for this reaction is: CH3COOH + CH3CH2OH ------> CH3COOCH3 + H2O
2 CH3CH2OH → CH3CH2OCH2CH3 + H2O (on 120'C)
CH3CH2OOCCH3 + H2O ===> CH3CH2OH + CH3COOH
HClO + H2O--> H3O + + NO2- since the H2O is a stronger base than NO2, it gets the protons, making it positive.
