Bond Length of HF Molecule
When two atoms form a covalent bond, they share their electrons. The electrons are attracted to both positively charged nuclei and are held in place by the attraction. The distance between two atoms bonded together is known as the bond length.
Electronegativity
Electronegativity is the ability of an atom to attract electrons towards itself in a chemical bond. Fluorine (F) is the most electronegative element with an electronegativity value of 4.1, while hydrogen (H) has an electronegativity value of 2.1.
Bond Length of H-H Molecule
The bond length of an H-H molecule is 0.64 Å. Hydrogen is a nonpolar molecule, and the bond between the two hydrogen atoms is a nonpolar covalent bond. The bond is nonpolar because the electronegativity difference between the two atoms is zero. The two atoms share the electrons equally, and the electrons spend equal time around each nucleus.
Bond Length of F-F Molecule
The bond length of an F-F molecule is 1.2 Å. Fluorine is also a nonpolar molecule, and the bond between the two fluorine atoms is a nonpolar covalent bond. The bond is nonpolar because the electronegativity difference between the two atoms is zero. The two atoms share the electrons equally, and the electrons spend equal time around each nucleus.
Bond Length of HF Molecule
The bond length of an HF molecule can be calculated using the electronegativity values of H and F and the bond length of H-H and F-F molecules. The electronegativity difference between H and F is 2.0 (4.1-2.1). This indicates that the bond between H and F is polar, with the electron density being more towards the F atom. Therefore, the H-F bond has a dipole moment.
The bond length of HF is expected to be less than the bond length of F-F (1.2 Å) and more than the bond length of H-H (0.64 Å) due to the difference in electronegativity values. The bond length of HF is 0.92 Å.
The dipole moment of the HF molecule is 1.82 D, which indicates that the molecule is polar. The H-F bond is a polar covalent bond, and the electrons are not shared equally between the two atoms. The electron density is more towards the F atom, making it partially negative, while the H atom is partially positive.
The bond length of HF is shorter than expected due to the strong attraction between the partially positive H atom and the partially negative F atom. This attraction results in a shorter bond length compared to the expected value based on the electronegativity difference alone.
