A student Babita Phogat went to meet his friend Geeta Phogat, where she saw that Geeta Phogat was doing the study of a partcular chemistry book. But she could not find the theoretical value of bond length in H-F although she found that radius of hydrogen and Fluorine are 0.37 Å and 0.72 Å respectively & electronegativity of F & H are 4.0 and 2.1 respectively. What is bond length of H-F bond.

Answer» `1.09` `1.784` `0.92` `0.46` SOLUTION :`d_(H - F) = 0.37 + 0.72 - 0.09 \|4 - 2.1\|` `= 1.09 - 0.17` `= 0.92 Å`
