प्रश्न
Define the bond length.
उत्तर १
Bond length is defined as the equilibrium distance between the nuclei of two bonded atoms in a molecule.
Bond lengths are expressed in terms of Angstrom (10–10 m) or picometer
(10–12 m) and are measured by spectroscopic X-ray diffractions and electron-diffraction techniques.
In an ionic compound, the bond length is the sum of the ionic radii of the constituting atoms (d = r+ + r–). In a covalent compound, it is the sum of their covalent radii (d = rA+ rB).
उत्तर २
Bond-length: It is the equilibrium distance between the nuclei of two bonded atoms in a molecule. Bond-lengths are measured by spectroscopic methods
