Question:
Beryllium shows diagonal relationship with aluminium. Which of the following similarity is incorrect?
Beryllium shows diagonal relationship with aluminium. Which of the following similarity is incorrect?
Show Hint
Diagonal relationships show similarities but not identity in behaviour.
Updated On: Mar 20, 2026
- Be forms beryllates and Al forms aluminates
- BeO(OH)₂ like Al(OH)₃ is basic
- Be like Al is rendered passive by HNO₃
- Be₂C like Al₄C₃ yields methane on hydrolysis
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Be and Al show diagonal relationship.
Step 2: Be is not rendered passive by nitric acid unlike aluminium.
