Pick the incorrect statement among those given below.

Options

  1. AMultiple covalent bonds are shorter, than single covalent bonds between same set of atoms.
  2. BBond strength varies inversely with bond length.
  3. CBond order of isoelectronic species will be same.
  4. DBond enthalpy increases with increasing bond length.

Correct answer

D. Bond enthalpy increases with increasing bond length.

Step-by-step solution

Bond enthalpy decreases with increasing bond length as the intermolecular force of attraction decreases with increase in the distance between the constituent particles.
