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 $pπ - dπ$ bond formation.

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

TestHub · Accepted Answer

Statement I, SnO , PbO , SnO 2 , PbO 2 : Amphoteric CO 2 , SiO 2 , GeO 2 , GeO : Acidic CO : Neutral According to Statement II, Carbon does not have d-orbitals so can not form pπ - dπ Bond with itself. Due to properties of catenation and pπ - pπ bond formation, carbon is able to show allotropic forms. Allotropic forms of carbon can be crystalline and amorphous. Diamond and graphite are two well-known crystalline forms of carbon. Hence option C is the answer.
