Vedclass · Answer

(A) The bond length is defined as the average distance between the centers of the nuclei of two bonded atoms in a molecule. It depends on factors such as atomic size, hybridization, and electronegativity difference. As the atomic size increases, the bond length generally increases. Comparing the covalent radii of the atoms involved: $C-C$ bond length is approximately $154 \ pm$. $C-H$ bond length is approximately $109 \ pm$. $C-N$ bond length is approximately $147 \ pm$. $C-O$ bond length is approximately $143 \ pm$. Therefore, the $C-C$ bond has the longest bond distance among the given options.
