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.
A. `1.09`
B. `1.784`
C. `0.92`
D. `0.46`

Correct Answer - C
`d_(H - F) = 0.37 + 0.72 - 0.09 |4 - 2.1|`
`= 1.09 - 0.17`
`= 0.92 Å`
