JEE Mains · Chemistry · STD 11 -p-Block elements - I
The correct statements among \(I\) to \(III\) regarding group \(13\) element oxides are, \(I\). Boron trioxide is acidic \(II\). Oxides of aluminium and gallium are amphoteric \(III\). Oxides of indium and thallium are basic
- A \(I, II\) and \(III\)
- B \(II\) and \(III\) only
- C \(I\) and \(III\) only
- D \(I\) and \(II\) only
Answer & Solution
Correct Answer
(A) \(I, II\) and \(III\)
Step-by-step Solution
Detailed explanation
\(B_2O_3\) is acidic in nature \(Al_2O_3\) and \(Ga_2O_3\) are amphoteric Oxides of \(In\) and \(Tl\) are basic in nature. Because the metallic character of the elements increases on moving down the group.
