Statement (I) : SiO2 and GeO2 are acidic while SnO and PbO are amphoteric in nature.

Question

Given below are two statements : 

Statement (I) : \(SiO_2\) and \(GeO_2\) are acidic while SnO and PbO are amphoteric in nature. 

Statement (II) : Allotropic forms of carbon are due to property of catenation and \(p\pi -d\pi\) bond formation. 

In the light of the above statements, choose the most appropriate answer from the options given below: 

(1) Both Statement I and Statement II are false 

(2) Both Statement I and Statement II are true 

(3) Statement I is true but Statement II is false 

(4) Statement I is false but Statement II is true

Answer 1

(3) Statement I is true but Statement II is false 

\(SiO_2\) and \(GeO_2\) are acidic and SnO, PbO are amphoteric. 

Carbon does not have d-orbitals so can not form \(p\pi -d\pi\) Bond with itself. Due to properties of catenation and \(p\pi -p\pi\) bond formation. carbon is able to show allotropic forms.
