Calculate the bond length of `C-X` bond, if `C-C` bond length is `1.54 Å, X -X` bond length is `1.00 Å` and electronegativity values of `C` and `X` are `2.0` and `3.0` respectively.

Explanation

(1) C - C bond length = 1.54 Å
`r_(C) = (1.54)/(2) = 0.77` Å
`r_(X) = (1.00)/(2) = 0.50` Å
(2) C - X bond length
`d_(C - X) = r_(C) + r_(X) - 0.09 (X_(x) - X_(C))`
`0.77 + 0.50 - 0.09 ( 3 - 2)`
`= 0.77 + 0.50 - 0.09 xx 1`
`=1.27 - 0.09 = 1.18` Å
Thus C - X bond length is 1.18 Å
