Question

Beryllium is diagonally related to the element \(X\) and lithium is diagonally related to the element \(Y\). The nature of oxides of \(X\) and \(Y\) are respectively

• A. Amphoteric, acidic
• B. Amphoteric, basic
• C. Acidic, amphoteric
• D. Amphoteric, neutral

Hint:

Diagonal relationships: \[ \boxed{ \mathrm{Li \leftrightarrow Mg} } \] \[ \boxed{ \mathrm{Be \leftrightarrow Al} } \] Also, \[ \mathrm{Al_2O_3} \text{ is amphoteric, while } \mathrm{MgO} \text{ is basic.} \]

Answer 1

The Correct Option is B

Step 1: Identify the elements using diagonal relationship. Beryllium is diagonally related to \[ \boxed{\mathrm{Aluminium\;(Al)}}. \] Lithium is diagonally related to \[ \boxed{\mathrm{Magnesium\;(Mg)}}. \]

Step 2: Identify the nature of their oxides. Aluminium oxide, \[ \mathrm{Al_2O_3}, \] is \[ \boxed{\text{amphoteric}}. \] Magnesium oxide, \[ \mathrm{MgO}, \] is \[ \boxed{\text{basic}}. \] Hence, \[ \boxed{\text{Amphoteric,\; basic}} \] Therefore, \[ \boxed{(B)} \] is the correct answer.
