Question : 134 of 160

Marks: +1, -0

Assertion(A): The maximum covalency of Si and Ge is 6 bur That of carbon is 4.
Reason (R): Due to the presence of d-orbitals in Si and Ge. both these elements can undergo sp3d2 hybridisation and covalency of 6 is possible. Carbon has no d-orbitals in it and hence its covalency is 4.

(A) and (R) are correct and (R) is the correct explanation of (A)
(A) and (R) are correct but (R) is not the correct explanation of (A)
(A) is correct but (R) is not correct
