- B I, III
- C II, III
- D I, II
Answer & Solution
Correct Answer
(B) I, III
Step-by-step Solution
Detailed explanation
At \(0 \mathrm{~K}\), the entropy of pure crystalline materials is zero. \(\therefore\) The statement (I) is correct as entropy approach zero, at absolute zero. Statement (II) entropy for the process,…

Reason (R): Due to the presence of d-orbitals in Si and Ge, both these elements can undergo \(\mathrm{sp}^3 \mathrm{~d}^2\) hybridisation and covalency of 6 is possible. Carbon has no d-orbitals in it and hence its covalency is 4.
