Summary
This study investigates if fluorinated organic compounds can form hydrogen bonds. Findings confirm that fluoroorganics like CH3F can form hydrogen bonds, similar to water molecules.
Area of Science:
- Chemical Physics
- Computational Chemistry
- Organic Chemistry
Background:
- Fluorinated organic compounds are vital in pharmaceuticals and agriculture.
- Fundamental properties of fluoroorganics, such as hydrogen bonding, remain poorly understood.
Purpose of the Study:
- To determine if fluoroorganics can participate in hydrogen bonding.
- To compare the hydrogen bonding capabilities of fluoroorganics with well-established systems.
Main Methods:
- Comparative analysis of the CH3F···HOH complex with ten other molecular dimers.
- Evaluation of binding energy, geometry, vibrational frequencies, charge transfer, and electron density topology.
Main Results:
- All analyzed features indicate the formation of a hydrogen bond in the CH3F···HOH complex.
- The hydrogen bond in CH3F···HOH is comparable, though slightly weaker, than that in the water dimer.
Conclusions:
- Fluoroorganics are capable of forming hydrogen bonds.
- The hydrogen bonding characteristics of fluoroorganics are similar to those of water.

01:04Hydrogen Bonds
A hydrogen bond is formed when a weakly positive hydrogen atom already bonded to one electronegative atom (for example, the oxygen in the water molecule) is attracted to another electronegative atom from another polar molecule, such as water (H2O), hydrogen fluoride (HF), or ammonia (NH3). The huge electronegativity difference between the H atom (2.1) and the atom to which it is bonded (4.0 for an F atom, 3.5 for an O atom, or 3.0 for an N atom), combined with the very small size of an H atom...
00:26Hydrogen Bonds
Hydrogen bonds are weak attractions between atoms that have formed other chemical bonds. One of these atoms is electronegative, like oxygen, and has a partial negative charge. The other is a hydrogen atom that has bonded with another electronegative atom and has a partial positive charge.
Hydrogen Bonds Control the World!
Because hydrogen has very weak electronegativity when it binds with a strongly electronegative atom, such as oxygen or nitrogen, electrons in the bond are unequally shared.

03:01Halogens
Group 17 elements, known as halogens, are nonmetals. At room temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine a solid. Astatine is a highly unstable radioactive element, so currently, most of its properties are unknown due to its short half-life. Tennessine is a synthetic element also predicted to be in this group.

03:13Intermolecular Forces
Atoms and molecules interact through bonds (or forces): intramolecular and intermolecular. The forces are electrostatic as they arise from interactions (attractive or repulsive) between charged species (permanent, partial, or temporary charges) and exist with varying strengths between ions, polar, nonpolar, and neutral molecules. The different types of intermolecular forces are ion–dipole, dipole–dipole, hydrogen bonds, and dispersion; among these, dipole–dipole, hydrogen bonds, and dispersion...
