Which one of the following properties has same value for \(\mathrm{H}_2\) and \(\mathrm{D}_2\) ?
- A Density
- B Enthalpy of bond dissociation
- C Bond length
- D Melting point
Answer & Solution
Correct Answer
(C) Bond length
Step-by-step Solution
Detailed explanation
Bond length depends upon the electrostatic force of attraction. Substituting a different isotope in the atom should not change the bond length. Since, the electrical environment around the isotope is identical.
