Which one of the following has longest covalent bond distance?
Which one of the following has longest covalent bond distance?
$\mathrm{C}-\mathrm{C}$
$\mathrm{C}-\mathrm{H}$
$\mathrm{C}-\mathrm{N}$
$\mathrm{C}-\mathrm{O}$
Solution
The average distance between the centre of nuclei of the two bonded atoms in a molecule is known as bond length. It depends upon the size of atoms, hybridisation, steric effect, resonance etc.
Usually bond length of polar bond is smaller as compared to a non-polar bond. Therefore, $\mathrm{C}-\mathrm{C}$ bond length is longest among given options.
