$C-C$

Vedclass · Answer

(C) Bond length is approximately the sum of the covalent radii of the bonded atoms.
Using the approximate covalent radii: $r_H \approx 0.37 \ \mathring{A}$,$r_C \approx 0.77 \ \mathring{A}$,$r_N \approx 0.75 \ \mathring{A}$,$r_O \approx 0.73 \ \mathring{A}$.
Calculating the bond lengths:
$C-C \approx 0.77 + 0.77 = 1.54 \ \mathring{A}$
$C-N \approx 0.77 + 0.75 = 1.52 \ \mathring{A}$
$C-O \approx 0.77 + 0.73 = 1.50 \ \mathring{A}$
$C-H \approx 0.77 + 0.37 = 1.14 \ \mathring{A}$
Comparing these values,the $C-C$ bond has the maximum bond length.
