JEE Main 1 February 2024, Shift 2, Chemistry Q67

Question 67 of 90 in this shift, Chemistry question 7 of 30, Section A.

Given below are two statements : Statement (I) : SiO2\mathrm{SiO_2} and GeO2\mathrm{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 pπp\pi-dπd\pi bond formation. In the light of the above statements, choose the most appropriate answer from the options given below :
  1. (1)Both Statement I and Statement II are true
  2. (2)Both Statement I and Statement II are false
  3. (3)Statement I is true but Statement II is falseOfficial answer
  4. (4)Statement I is false but Statement II is true
