JEE Mains · Chemistry · STD 11 -p-Block elements - I
Given below are two statements: Statement \((I)\) : \(\mathrm{SiO}_2\) and \(\mathrm{GeO}_2\) are acidic while \(\mathrm{SnO}\) and \(\mathrm{PbO}\) are amphoteric in nature. Statement \((II)\) : Allotropic forms of carbon are due to property of catenation and \(\mathrm{p} \pi-\mathrm{d} \pi\) 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
Answer & Solution
Correct Answer
(C) Statement \(I\) is true but Statement \(II\) is false
Step-by-step Solution
Detailed explanation
\(\mathrm{SiO}_2\) and \(\mathrm{GeO}_2\) are acidic and \(\mathrm{SnO}, \mathrm{PbO}\) are amphoteric. Carbon does not have d-orbitals so can not form \(\mathrm{p} \pi-\mathrm{d} \pi\) Bond with itself. Due to properties of catenation and \(\mathrm{p} \pi-\mathrm{p} \pi\) bond…
