Consider the following statements:
1. Maximum covalency of carbon is 4, whereas maximum covalency of silicon is 6.
2. The maximum covalency of an element is limited to 6.
Which of the statements given above is /are correct ?
-
- 1 only
- 2 only
- Both 1 and 2
- Neither 1 nor 2
Correct Option: A
Carbon and Silicon both is belongs to IVth group and carbon have maximum valency of 4.
C : 2, 4
Si : 2, 8, 4
But Si have vacant d-orbitals and can be used to accomodate more electrons. Thus, the maximum cavalency of Si can be 6.
