Question

Statement-I : SiO₂ and GeO₂ are acidic, SnO and PbO are amphoteric 

Statement-II : Allotropes of carbon are formed due to catenation and dπ-pπ bond 

(1) Statement-I and Statement-II both correct 

(2) Statement-I and Statement-II both incorrect 

(3) Statement-I correct and Statement-II both incorrect 

(4) Statement-I and Statement-II both incorrect

Answer 1

(3) Statement-I correct and Statement-II both incorrect 

SiO₂ and GeO₂ are acidic and SnO, PbO are amphoteric 

Carbon does not have d orbital cannot for dπ-dπ bond
