P Block Elements Group 13 And 14 Question 2
Question 2 - 2024 (01 Feb Shift 2)
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 (3)
Solution
$SiO _2$ 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.
