Which compound has the strongest hydrogen bonding between its molecules? 1. HBr 2. HF 3. HCl 4. HI You can compare the strength of the hydrogen bonding by comparing the electronegativities of the other elements. All the four elements, Br, F, Cl and I belong to the same group in the periodic table: group 17 named halogens. Then the kind of bonding they form is similar: polar covalent. You must know the trend of the electronegativities in the periodic table. Electronegativity decrease when you down across a group. Then the electronegativity of F is the higher of the group (indeed, it is the highest of all the 118 elements) . The higher the electronegativity the stronger the attraction that the halogen attracts the electrons and the stronger the hydorgen bonding. Then, the conclusion is that HF has the strongest hydrogen bonding.

Hydrogen bond Water – Hydrogen Bonds The slightly negative oxygen atom of one water molecule is attracted to the slightly positive hydrogen atoms of nearby water molecules, forming hydrogen bonds. Each water molecule can form hydrogen bonds with up to four neighbors. Hydrogen bonds hold water molecules together. They form, break, and reform with great frequency. Extraordinary Properties that are a result of hydrogen bonds: Cohesive and adhesive behavior Resists changes in temperature

Hydrogen Bonding in Water (1) The hydrogen atoms are not only covalently attached to their oxygen atoms but also attracted towards other nearby oxygen atoms. This attraction is the basis of the 'hydrogen' bonds. The water hydrogen bond is a weak bond, never stronger than about a twentieth of the strength of the O-H covalent bond.

Intermolecular Forces The unique properties of water are largely due to the strong hydrogen bonding that occurs between its molecules. In the following diagram the hydrogen bonds are depicted as magenta dashed lines. The molecule providing a polar hydrogen for a hydrogen bond is called a donor.

Tetrafluoromethane In the one carbon organofluorine compounds represented by molecules of fluoromethane, difluoromethane, trifluoromethane, and tetrafluoromethane, the carbon–fluorine bonds are strongest in tetrafluoromethane.etrafluoromethane, like other fluorocarbons, is very stable due to the strength of its carbon–fluorine bonds. The bonds in tetrafluoromethane have a bonding energy of 515 kJ⋅mol −1. As a result, it is inert to acids and hydroxides.

Hydrogen Bonding This is why the boiling point of water is higher than that of ammonia or hydrogen fluoride. In the case of ammonia, the amount of hydrogen bonding is limited by the fact that each nitrogen only has one lone pair. In a group of ammonia molecules, there aren't enough lone pairs to go around to satisfy all the hydrogens.

Hydrogen Bonding in Water (1) In water's hydrogen bonds, the hydrogen atom is covalently attached to the oxygen of a water molecule (492.2145 kJ ˣ mol-1 [350]) but has (optimally) an additional attraction (about 23.3 kJ mol-1 [168]. This is the energy (δH) required for breaking the bond and completely separating the atoms.

Which Chemical Bond is Stronger: Ionic vs. Covalent Bonds The simplest way to determine which of the ionic bonds are strongest is to examine the electronegativities of the anion (the negative portion of a compound) and its cation (the positive portion of the compound). Linus Pauling developed a list of numbers that quantified the property of electronegativity.

Lesson 9: Determining Bond Type Intermolecular Bonds (Molecular Materials) Of these three intermolecular bond types, the strongest are hydrogen bonds. For a given size of molecule, chemicals that use hydrogen bonds will tend to have higher melting points and boiling points than chemicals that use the weaker dipole-dipole or van der Waals bonds.

Intramolecular and intermolecular forces Hydrogen bonding: This is a special kind of dipole-dipole interaction that occurs specifically between a hydrogen atom bonded to either an oxygen, nitrogen, or fluorine atom. The partially positive end of hydrogen is attracted to the partially negative end of the oxygen, nitrogen, or fluorine of another molecule. Hydrogen bonding is a relatively strong force of attraction between molecules, and considerable energy is required to break hydrogen bonds.

General Chemistry/Intermolecular bonds When comparing boiling points of the non-polar gases, like the noble gases, the gas with the largest radius will have the highest points because it has the most potential for van der Waals forces. Ionic compounds can be compared using Coulomb's Law. Look for substances with high ionic charges and low ionic radii.

CHEMICAL BONDING AND COMPOUND FORMATION A covalent HH bond is the net result of attractive and repulsive electrostatic forces. The nucleuselectron attractions (blue arrows) are greater than the nucleusnucleus and electronelectron repulsions (red arrows), resulting in a net attractive force that holds the atoms together to form an H2 molecule.

Hydrogen Bonding If you liken the covalent bond between the oxygen and hydrogen to a stable marriage, the hydrogen bond has just good friends status. Water as a perfect example of hydrogen bonding. Notice that each water molecule can potentially form four hydrogen bonds with surrounding water molecules. There are exactly the right numbers of δ+ hydrogens and lone pairs so that every one of them can be involved in hydrogen bonding.

What Causes Hydrogen Bonding? Hydrogen bonding occurs between a hydrogen atom and an electronegative atom (e.g., oxygen, fluorine, chlorine). The bond is weaker than an ionic bond or a covalent bond, but stronger than van der Waals forces (5 to 30 kJ/mol). A hydrogen bond is classified as a type of weak chemical bond.

Hydrogen Bond Examples Hydrogen bonds happen in alcohols. As a matter of fact, any molecule that contains a hydrogen atom attached to an atom of nitrogen or oxygen is capable of such a bond. Ethanol is one such alcohol that features hydrogen bonds. Ammonia is an example of hydrogen bonding. In the case of ammonia, however, the hydrogen bond happens to be relatively weak.

Hydrogen Bond Examples (Chemistry) 1 hydrofluoric acid - HF - Hydrofluoric acid forms what is called a symmetric hydrogen bond, which is stronger than the regular hydrogen bond. This type of bond also forms in formic acid. 2  proteins - Hydrogen bonds result in protein folding, which helps the molecule maintain stability and assume a functional configuration.

Chem152 Final Exam: 151 Review The covalent with hydrogen bonding has the second highest b.p. because hydrogen bonding is the strongest covalent bond. Finally, the nonpolar covalent bond with dispersion forces has the lowest b.p. because there isn't much holding the molecules together to keep them from changing phase. Pretend you have 2 covalent polar bonds, each with London dispersion forces and dipole-dipole.

- From strongest to weakest, the intermolecular forces rank in the following way: Strongest: Hydrogen bonding. This occurs when compounds contain #O-H#, #N-H#, or #F-H# bonds. Though referred to as hydrogen bonding, it's not a real bond but just a really strong intermolecular force. Less strong: Dipole-dipole forces.
