Given below are two statements:
Statement (I): SiO₂ and GeO₂ 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:
Statement (I): SiO₂ and GeO₂ 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:
- (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✓ Correct
- (D)Statement I is false but Statement II is true
Answer: (C)
Solution
Moving down group 14, oxide character shifts from acidic to amphoteric as metallic character increases: and are acidic, while and are amphoteric — Statement I is true. Carbon's allotropes (diamond, graphite, fullerenes) arise from its ability to catenate and to form - bonds with itself; carbon has no available d-orbitals in its valence shell, so it cannot form - bonds — Statement II, which attributes the allotropy to - bonding, is false.
