Question

All the elements in group 14 exhibit tetravalency.

(a) true

(b) false

I got this question in quiz.

Origin of the question is p-Block Elements in chapter p-Block Elements of Chemistry – Class 11

Answer 1

Correct option is (a) true

The explanation is: In the case of carbon, 406 KJ per mole of energy is required for promotion of 2s electron to 2p. The formation of two extra bonds provides this energy, therefore we can say that all the elements exhibit tetravalency in group 14. So the above statement is true.
