A student went to meet his friend, where he saw that his friend was doing the study of a particular chemistry book. But he could not find the theoretical value of bond length in H-F but the found that `r_(H)` and `r_(F)` are `0.37Å` and `0.72Å` respectively and electronegativity of F and 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`

Text Solution

Verified by Experts

The correct Answer is:
C
`B.L = 0.37 +0.72 - 0.09 xx (4-2.1) = 0.92 Å`
