AP EAMCET · Chemistry · p Block Elements (Group 13 & 14)
Assertion(A): The maximum covalency of Si and Ge is 6 but that of carbon is 4.
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.
The correct answer is:
- A (A) and (R) are correct and (R) is the correct explanation of \((\mathrm{A})\)
- B (A) and (R) are correct but \((\mathrm{R})\) is not the correct explanation of \((\mathrm{A})\)
- C (A) is correct but \((\mathrm{R})\) is not correct
- D (A) is not correct but (R) is correct
