Answer to Question #54540 in General Chemistry for jagan nath
in HF the experimental bond length value is less than the sum of covalent radii?
The experimental bond length for HF was found to be 0.917 angstroms on the NIST website. http://www.uwosh.edu/faculty_staff/gutow/Chem_371_S09/SNRE%20Webpage/HF%20Calculations/HF%20Calculations.html The sum of covalent radii 73pm. R=73*10^-12 m = 7.2*10^-11 m. So, in HF the experimental bond length value is less than the sum of covalent radii.
