Which one of the following has longest covalent bond distance?

Options

  1. AC - C
  2. BC - H
  3. CC - N
  4. DC - O

Correct answer

A. C - C

Step-by-step 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, C - C bond length is longest among given options.
