Bond length is the experimentally determined average distance between two bonded atoms. Bonded atoms vibrate due to thermal energy available in the surroundings. Bond lengths are typically in the range of 100-200 pm (1-2 Å). As a general trend, bond length decreases across a row in the periodic table and increases down a group. Bond Lengths and Enthalpies .

In liquid water, the mean O-H length is about 0.097 nm, the mean H-O-H angle is about 106°, and This is called 'hydrogen-bonding' as the hydrogen atoms appear to hold on to both O atoms.

In molecular geometry, bond length or bond distance is defined as the average distance between nuclei of two bonded atoms in a molecule.It is a transferable property of a bond between atoms of fixed types, relatively independent of the rest of the molecule.

Physical Properties: Bond Length, Bond Strength & Acidity. A. Bond Lengths: mostly dependent on atomic size, bond order, and hybridization sp3 sp2 sp. C H. The bond lengths range from the shortest of 74 pm for \(\ce{H-H}\) to some 200 pm for large atoms, and the bond energies depend on bond order and lengths. Half of the bond length of a single bond of two similar atoms is called covalent radius. The sum of two covalent radii of two atoms is usually the single bond length. Referring to the table above, a double bond between carbon and oxygen has a bond length of approximately 67 + 57 = 124 pm and a triple bond between carbon and oxygen has a bond length of approximately 60 + 53 =113 pm. In real world, distance beetwen atoms are not constant, because atoms in mocelules are in constant motion. Effectively bonds are in longer-shorter cycle, oscillating around some particular length. In general, the length of the bonds is a property of a whole molecule. Bond length is commonly measured in either angstroms or picometers. There are charts that reveal the estimated bond length (radii in angstroms or picometers) between two given atoms, according to bond type (i.e. single, double, or triple bond). According to the chart, the covalent radius of carbon double bond is 67 picometers and that of oxygen double bond is 57 picometers. Therefore, the bond length of carbon dioxide is approximately 124 picometers (57 pm+ 67 pm). Bond length is the experimentally determined average distance between two bonded atoms. Bonded atoms vibrate due to thermal energy available in the surroundings. Bond lengths are typically in the range of 100-200 pm (1-2 å).
