Question

Given below are two statements : Statement (I) : SiO2 and GeO2 are acidic while SnO and PbO are amphoteric in nature. Statement (II) : Allotropic forms of carbon are due to property of catenation and p-d bond formation. In the light of the above statements, choose the most appropriate answer from the options given below:

(A) Both Statement I and Statement II are false
(B) Both Statement I and Statement II are true
(C) Statement I is true but Statement II is false
(D) Statement I is false but Statement II is true

Correct answer: C. SiO2 and GeO2 are acidic and SnO, PbO are amphoteric. Carbon does not have d-orbitals so can not form p-d Bond with itself. Due to properties of catenation and p-p bond formation. carbon is able to show allotropic forms.
