Hydrogen bonding in alcohols An alcohol is an organic molecule containing an -O-H group. Any molecule which has a hydrogen atom attached directly to an oxygen or a nitrogen is capable of hydrogen bonding. Such molecules will always have higher boiling points than similarly sized molecules which don't have an -O-H or an -N-H group. The hydrogen bonding makes the molecules "stickier", and more heat is necessary to separate them. Ethanol, CH3CH2-O-H, and methoxymethane, CH3-O-CH3, both have the same molecular formula, C2H6O. ---- Note: If you haven't done any organic chemistry yet, don't worry about the names.

They have the same number of electrons, and a similar length to the molecule. The van der Waals attractions (both dispersion forces and dipole-dipole attractions) in each will be much the same. However, ethanol has a hydrogen atom attached directly to an oxygen - and that oxygen still has exactly the same two lone pairs as in a water molecule. Hydrogen bonding can occur between ethanol molecules, although not as effectively as in water. The hydrogen bonding is limited by the fact that there is only one hydrogen in each ethanol molecule with sufficient + charge. Credit to: http://www.chemguide.co.uk/atoms/bonding/hbond.html
What else can I help you with?
Hydrogen bonding occurs in molecules where hydrogen is bonded to what elements fluorine carbon oxygen nitrogen hydrogen boron?
the hydrogen bonding is possible in oxygen, nitrogen,and fluorine
Is hydrogen bonding is a type of bonding or not?
Hydrogen bonding is a type of intermolecular force of attractionAdded:This is between molecules.It is not as strong as chemical bonding within molecules (intramolecular) though.
Why hydrogen bonding is not present in hydrogen sulphide?
Hydrogen bonding occurs between hydrogen atoms and a highly electronegative atom like oxygen, nitrogen, or fluorine. In hydrogen sulfide (H2S), sulfur is less electronegative than oxygen, so the hydrogen bonding is weaker and not significant enough to cause hydrogen bonding in H2S.
Why hydrogen chloride does not form hydrogen bond?
According to the definition, to form a hydrogen bond, a bond with hydrogen and another element should have a higher value for electronegativity such as H-N, H-O and H-F. H-Cl does not meet with sufficient polarity to form a hydrogen bond.
Why is hydrogen bonding only possible with hydrogen?
Hydrogen bonding is possible with hydrogen because of its small size and high electronegativity, which results in a highly polar covalent bond. This allows hydrogen to form attractive interactions with other highly electronegative atoms like oxygen, nitrogen, and fluorine, leading to the formation of hydrogen bonds.
Does table salt form from sodium and chloride via hydrogen bonding?
No, table salt forms from sodium and chlorine via ionicbonding.Hydrogen bonding is technically not a form of bonding but a type of intermolecular force in compounds where hydrogen is bonded to nitrogen, oxygen, or fluorine.
Why water has boiling point of 100 degrees while hydrogen cl has a boiling point of 115 degrees?
Water has hydrogen bonding between molecules, which requires more energy to break compared to the weaker van der Waals forces between hydrogen chloride molecules. The stronger hydrogen bonding in water results in a higher boiling point compared to hydrogen chloride.
Hydrogen Chloride why is it a covalent bond and not hydrogen bond?
Hydrogen chloride (HCl) forms a covalent bond because it consists of the sharing of electrons between hydrogen and chlorine atoms. A hydrogen bond is a specific type of interaction that occurs between a hydrogen atom bonded to an electronegative atom (such as oxygen or nitrogen) and another electronegative atom. In the case of HCl, the bond between hydrogen and chlorine is based on electron sharing, not on hydrogen bonding.
What are the intermolecular forces in ammonium chloride?
In ammonium chloride, the main intermolecular forces present are ionic bonds between the positively charged ammonium ions and the negatively charged chloride ions. Additionally, there are weaker hydrogen bonds between the ammonium ions and chloride ions.
Why does gasoline interfere with the hydrogen bonding between ethanol molecules?
Possible because gasoline is nonpolar.
Why ethyl alcohol is a liquid while ethyl chloride is a gas?
Ethyl alcohol is a liquid because strong hydrogen bonding in it brings the molecules closer together while methyl chloride does not form hydrogen bonding,weaker forces exist between molecules of methyl and chloride due to which they lie at distance from each other till gas form.
What type of bonding for the potassium chloride?
Potassium chloride forms ionic bonding. Ionic bonding is the electrostatic attraction between positively charged potassium ions and negatively charged chloride ions.
What type of bonding is between magnesium and hydrochloric acid?
Hydrogen chloride has a covalent bond.
What type of bonding holds the two strands of DNA together and why is this important?
hydrogen bonding between the two bases present on two strands of dna hold the two strands. If there was no hydrogen bonding then doublex helix structure of dna would not be possible
Hydrogen bonding occurs in molecules where hydrogen is bonded to what elements fluorine carbon oxygen nitrogen hydrogen boron?
the hydrogen bonding is possible in oxygen, nitrogen,and fluorine
Table salt is the result of a hydrogen bond?
Table salt, or sodium chloride, is formed by the ionic bonding between a sodium ion (Na+) and a chloride ion (Cl-) rather than a hydrogen bond. This type of bonding involves the transfer of electrons between the atoms, resulting in an electrostatic attraction that holds the ions together in a crystalline structure.
What is the type of bonding in the compound sodium chloride?
Sodium chloride has ionic bonding, which is the electrostatic attraction between oppositely charged ions (sodium cation and chloride anion). This type of bonding involves the transfer of electrons from one atom to another.
