Bond enthalpy of \(\mathrm{Ge}-\mathrm{Ge}\) bond is \(260 \mathrm{~kJ} \mathrm{~mol}^{-1}\). The bond enthalpies of Si-Si and \(\mathrm{Sn}-\mathrm{Sn}\) bonds in \(\mathrm{kJ} \mathrm{mol}^{-1}\) are respectively
- A 240,270
- B 297,297
- C 297,240
- D 200,348
Answer & Solution
Correct Answer
(C) 297,240
Step-by-step Solution
Detailed explanation
The \(\mathrm{Si}, \mathrm{Ge}\) and \(\mathrm{Sn}\) belong to third, fourth and fifth period of group 14 of periodic table. Moving down the group, size of atoms increases, so the bond length order is…
