Which among the following statements is false?
Options
- AG e ( O H ) 2 is amphoteric
- BG e C l 2 is more stable than G e C l 4
- CG e O 2 is weakly acidic
- DG e C l 4 in HCl forms [ G e C l 6 ] 2 - ions
Correct answer
B. G e C l 2 is more stable than G e C l 4
Step-by-step solution
For Ge, +2 oxidation state is less stable than +4, therefore, G e C l 2 is less stable than G e C l 4 . A. G e ( O H ) 2 has both acidic and basic properties. ( a ) G e ( O H ) 2 + 2 H C l → G e C l 2 + 2 H 2 O ( b ) G e ( O H ) 2 + K O H → K [ G e ( O H ) 3 ] C. Basicity of dioxides of group 14 increases on going down the group and hence, G e O 2 is weekly acidic. D. G e C l 4 + 2 H C l → H 2 [ G e C l 6 ] .
